Minecraft can't launch

[Lonexoli]

Since yesterday, I can't launch Minecraft. When I press the "Start" button, the game crashes before the window is created. The game used to work perfectly fine...

Not really sure what it could be, as I'm also on 1.16.4 and it still works for me. I also did a clean installation on a virtual machine with Kubuntu 20.10 with Wayland it works just fine there:

Is your log file incomplete by any chance? Can you please double-check: ~/.var/app/com.teamshiginima.ShiginimaLauncher/data/minecraft/logs/latest.log

I would also try renaming the com.teamshiginima.ShiginimaLauncher folder to something else (temporarily), then try running the launcher again so it creates a fresh Minecraft installation. If the game runs, then you can perhaps try copying your stuff from the older folder to the new one.

No problems on my end either

Thanks for the answer! What I sent is the entire log. Also, I tried what you said but I still have the same problem.

Well, it sounds like a recent system update (video driver, most likely) broke Flatpak. Did you try running flatpak update?

If you did, then please provide the following information:

• Linux distribution
• GPU
• Video driver and version
• Display server (X11 or Wayland)

And a list of installed Flatpak apps:

flatpak list

Thanks.

I tried flatpak update and it turns out that I just had to do some Nvidia updates.
