I can't sign into the xbox app on windows 10 PC

If you're talking about the xbox app on pc nothing there works.

I did all of those solutions and none of them worked, I am signed there to my Microsoft Store account but I can sign in to the gaming account and whenever I tried to take a game because I got ultimate it says "upgrade to ultimate" or something like that.

Nope, can't you just like log into my account or something and give me the code or the qr code from there? thats the best solution I can think of.

Considering not even uninstalling solved your problem, check out these solutions (it says it's for not opening app, but maybe it helps you):
