Meme transcription: Anakin & Padme
[Panel 1] Anakin tries selects “Update and shut down” from the Windows start menu.
[Panel 2] Padme, labeled as “Windows”, cheerily says: ”You mean ‘Update and restart’, right?”
[Panel 3] Anakin takes an annoyed look.
[Panel 4] Padme, still cheery, says “I’ll just ‘Update and Restart’.”
I've never used Mint and I don't get the hype. I didn't have to modify anything on endeavourOS for stuff to run. All I do on endeavourOS is yay to get updates and install via yay -S [pkgname].
On endeavourOS I run Steam via flatpak since it uses 32bit libraries, so I personally prefer it separate, but I used to have it non-flatpak and it worked normally.

There's a lot of results for Steam games not launching on Mint with hopefully something which may solve your issue. Sorry to be of no help. :(
No you’ve definitely been a great help…in convincing me to give arch a try
