First a check. Is the appimage file executable.
Main Menu as shown by PixLab is an application called Alacarte which I do not think is installed by default in a ubuntu 22.04 It is a menu modification utility for customising your ubuntu menu and can make entries as well - .desktop files.
Your basic .desktop file probably need a categories entry to put Gimp into the ubuntu menu structure although it should work without it.
The mistake is trying to start the desktop file as you would start an application ie. using dot-slash
Once you have that desktop file working, start Gimp from the ubuntu menu structure.
PS. Please don't use large text, not necessary, considered shouting by us old-timers, and makes replying a pain.
