If the error appeared after installing:
- Texture packs
- Cheats
- FPS mods

Try disabling them temporarily.
What I Usually Do
Whenever I encounter a new crash, I disable all mods first and test the game in its vanilla state. This quickly reveals whether a modification is causing the problem.

If possible:

This often fixes stubborn issues that seem unrelated.
Fix 7: Clear the Shader Cache
Shader cache corruption can lead to graphical glitches and crashes.

The next launch may take slightly longer as shaders are rebuilt, but many users report improved stability afterward.
Fix 8: Run Ryujinx as Administrator
Windows permission issues can sometimes prevent Ryujinx from accessing important files.
To Run as Administrator
- Right-click the Ryujinx executable.
- Select “Run as Administrator.”

You can also permanently enable administrator privileges through the Compatibility tab.
Fix 9: Reinstall Ryujinx Completely
