Ryujinx is one of the best Nintendo Switch emulators for PC. It runs many games well. But sometimes, it crashes right when you try to start a game.
This is a frustrating problem. You click play, and nothing happens — or the emulator just shuts down.
The good news? Most crashes have simple fixes. This guide covers every major cause and the right solution for each one.

Why Does Ryujinx Crash at Launch?
Before fixing the problem, it helps to know what caused it.
Here are the most common reasons:
- Outdated or broken GPU drivers
- Wrong graphics API (Vulkan vs OpenGL)
- Missing or outdated firmware and keys
- Corrupted shader cache
- Damaged game files
- Bad DLC or update files
- Hardware that struggles with high settings
The fix depends on the cause. Start from the top and work your way down. For a broader collection of solutions, the troubleshooting page covers many common errors.
Fix 1: Update Your GPU Drivers
This is the first thing to check. Old GPU drivers cause more emulator crashes than most people realize.
Each GPU brand has its own update tool:
| GPU Brand | Where to Update |
|---|---|
| NVIDIA | GeForce Experience or NVIDIA website |
| AMD | AMD Adrenalin Software |
| Intel | Intel Driver & Support Assistant |
After updating, restart your PC. Then open Ryujinx and try the game again.
This alone fixes the problem for many users.
Fix 2: Switch the Graphics API
Ryujinx supports two graphics backends: Vulkan and OpenGL. Some GPUs work better with one over the other.
If the game crashes on Vulkan, switch to OpenGL. If you are already on OpenGL, try Vulkan.
Here is how to do it:
- Open Ryujinx
- Click Settings
- Go to the Graphics tab
- Change the Graphics Backend
- Restart the emulator
Vulkan works better on most modern GPUs. But older cards sometimes crash with Vulkan. OpenGL is more stable in those cases. For more optimization tips, explore these graphics enhancements.
Fix 3: Clear the Shader Cache
Shader cache files help games load faster. But if they get corrupted, they cause crashes.
Clearing the cache forces Ryujinx to rebuild it fresh.
Steps to clear it:
- Open Ryujinx
- Right-click on the game
- Look for cache or shader options
- Delete the shader cache
The next time you start the game, it will rebuild the cache. The first launch will take longer than normal. That is expected. Give it a few minutes.
Fix 4: Check Firmware and Keys
Ryujinx needs proper system files to run Switch games. These include firmware files and encryption keys.
If they are missing or outdated, the emulator cannot launch the game correctly.
Check three things:
- Is the firmware version up to date?
- Are the key files present and valid?
- Does the game require a newer firmware version?
Outdated firmware is a silent cause of many launch failures. This is especially true after emulator updates.

Fix 5: Lower Graphics Settings
High settings put extra load on your GPU and CPU. If your hardware is not strong enough, the emulator can crash under that load.
Try these safer starting settings:
| Setting | Recommended Value |
|---|---|
| Resolution Scale | 1x (Native) |
| Graphics Backend | Default for your GPU |
| VSync | Enabled |
| Anti-Aliasing | Disabled or Default |
| Anisotropic Filtering | Default |
Once the game runs stable, you can slowly raise the settings. To see how different versions handle graphics, read this Ryujinx Canary vs Ryujinx comparison.
Fix 6: Disable Mods and Cheats
Mods and cheat files can break game compatibility. A single bad mod file can prevent a game from loading at all.
Try this:
- Disable all mods for the game
- Remove any active cheat files
- Launch the original, unmodified game
If it works, your mod files were the problem. Add them back one at a time to find which one is broken.

Fix 7: Remove Broken DLC or Updates
DLC and game updates must match the base game version. A mismatch will crash the game at startup.
If Ryujinx crashes after you added new DLC or an update:
- Disable the DLC or update
- Launch the base game alone
- If it works, your DLC or update file is the issue
- Replace it with the correct version
For proper installation steps, see this guide on how to install DLC and updates in Ryujinx. Also check the Tomodachi Life patch notes if that is the game you are troubleshooting.
Fix 8: Verify Your Game File
If only one game crashes and everything else works, the game file itself may be damaged.
Check these things:
- Is the file size correct?
- Was the download complete?
- Is the file format supported (NSP, XCI, etc.)?
A corrupt game file cannot be repaired. You will need a fresh copy to fix this.

Minimum Hardware to Run Ryujinx
Some hardware simply cannot handle certain games. Here is what Ryujinx recommends for a smooth experience:
| Component | Minimum | Recommended |
|---|---|---|
| CPU | Intel i5 / Ryzen 5 | Intel i7 / Ryzen 7 |
| RAM | 8 GB | 16 GB |
| GPU | GTX 970 / RX 570 | GTX 1060 / RX 580 or better |
| Storage | HDD | SSD |
Low-end hardware can run simple games. But demanding titles need a decent GPU and at least 16 GB of RAM. If your PC is below these specs, crashes are more likely. Browse the Ryujinx games guide to see which titles are less demanding.
Quick Summary Table
| Crash Symptom | Most Likely Fix |
|---|---|
| Crashes on every game | Update GPU drivers |
| Black screen then crash | Switch graphics API |
| Crash after emulator update | Clear shader cache |
| Crash on one game only | Verify or replace game file |
| Crash after adding DLC | Remove and replace DLC |
| Crash with mods | Disable all mods |
| Works at low settings only | Upgrade hardware or lower settings |
Final Thoughts
Ryujinx crashing at game launch is a common problem. But it is almost always fixable.
Start simple. Update your GPU drivers. Switch the graphics API. Clear the shader cache. These three steps solve most crashes.
If those do not work, check your firmware, keys, game files, and DLC. Work through the list one fix at a time.
Most users get their game running within a few steps. A clean setup with the right settings makes a big difference in stability. For a specific game like Tomodachi Life, you can also reference this guide on How to Play Tomodachi Life: Living the Dream on PC with Ryujinx for optimized settings.
