every time I try, the terminal says “the Wayland connection broke. did it die?” I have no idea what I’m doing. am I being an idiot? any help is greatly appreciated.
This forum is primarily for Flathub as an platform, so its not the ideal place to get help for app specific issues. If you look at the app page, you can find links to app-specific help resources.
That being said: From what I gathered, it seems like Qt 6 has some issues when both X11 and Wayland is available. See this issue for example.
You could disable the X11 socket with the argument --nosocket=x11.
To test this, run in your terminal:
flatpak run --nosocket=x11 org.prismlauncher.PrismLauncher
If it works with this command, you can make it permanent by running:
flatpak override --user --nosocket=x11 org.prismlauncher.PrismLauncher
