You can not start the application by trying to run the desktop file Why are you doing this ?
The standard ubuntu is not a great experience.
I do have a basic installed ubuntu 22.04 (VM)
I did have to install fuse to get the GIMP_AppImage-release-2.10.22-x86_64.AppImage to run
The gimp.desktop file is ok in ~/.local/share/applications.
