All other programs launch just fine, just Krita. I tried removing and putting the launcher back. When I click on the launcher there’s the bouncing icon next to my cursor but then nothing
How was krita installed ?
Is it a flatpak, is it an Appimage ?
Does it launch from elsewhere ?
from the application launcher context menu you can choose edit application and see what the program call out looks like for command line along with any arguments
if you try pasting into a console window you can see if it gives you any errors, be sure to include the arguments
