from your Neofetch shots, u have the Cinnamon desktop (DE) u dont need mate-term or caja.

what I find odd though is that the Window Manager (WM) shows up as Metacity, instead of the default Mutter

Mint 21.2 doesnt support Metacity

it supposed to come with Mutter

check their respective permissions, that they match precisely to all the other .desktop files already there (ie - root owned, etc etc)

did u install something else, that would have made caja and mate-term a dependency?

cuz those two are Mate core programs

so unless u install Mate-desktop-environment idk why it would need or care to have them

and even if u did, ur logging into Cinnamon DE right? so it shouldnt care whether those two are there or not there

check from ur login screen (there's a little circle to pick what desktop session ur intending to login to) and make sure ur on what ur supposed to be on .. log out now and check

ok login to Cinnamon, and hopefully it loads without issue?

i think it's the mutter thing

vs Metacity

something doesnt belong, and it's the latter

Might be time to install a completely different Desktop environment

like KDE Plasma

or reinstall from scratch

u can install xfce4.. uninstall cinnamon and ANY other one.. then run those purge commands at the top of this chat given you by killertofu, if u like xfce, stay on it, otherwise after that u can reinstall cinnamon alongside.

multistep repair.

yeah xfce whisker menu. install it

otherwise u get a plain menu or not even one

check in synaptic pkg mngr

windows key is called Super key in linux. Super L is the Left one.
