Cannot sign into Xbox Gamebar (help)

I didnt have that exact folder name but I only had one xbox identity provider folder. I deleted the accounts and cache and still cannot load xbox app or sign into the gamebar. No option to sign out or change accounts.

I solved it by signing up for the gamebar on the xbox insider app

I fixed the issue on my own. On this day i found out in xbox gamebar that i cannot log in there on social tab. It showed that they cannot sign me into xbox live (The system cannot find the file specified) so i fixed thanks to JeffreyCloutier in this dicussion https://answers.microsoft.com/en-us/windows/forum/all/the-system-cannot-find-the-file-specified-xboxbeta/b7d0ae26-f24f-460e-954e-65fa61641d0d

you can play with people on windows 10 version, xbox console version with the steam version. OP are you signing into the game with a valid microsoft account, also have you got gamebar running and signed in with that account too as gamebar is needed for some game invites.

because signing into the xbox app also requires the microsoft store and gamebar to use the same account or it will not work, the xbox app uses the store for purchases and downloads. if you don't want to sign into the other parts of windows then you cannot use the xbox app.

don't forget, windows is free and basically not an OS like old, it is now a service and you have to agree to the terms to use such service.
