Edit: I'm no longer looking for help with this. The issue seems to be with the app itself and I have submitted a bug report for the app on github.

Before you tell me I should try another n64 emulator, I have been using other emulators but I have a game that isn't working and I'm trying to run it in other emulators.

Anyways, if I try to run simple64 through the terminal, I get the error message:

Failed to load module "xapp-gtk3-module"

I tried to look into this and it seems that I'm supposed to install "xapp" but I'm getting the error message:

The following packages have unmet dependencies: xapp : Depends: libxapp1 (= 2.2.8-1) but 2.8.2+virginia is to be installed E: Unable to correct problems, you have held broken packages.

I tried to fix it with sudo apt --fix-broken install xapp but it's just giving me the same error message. Is there anything else I can try before I try another emulator?
