I'm not sure if this falls in "I've tried resizing just about everything..." but in case it doesn't:
Right click on the screen - select display settings.
Check your settings under scale and layout.
'Advanced scaling settings' will let you set a specific scale, and it's possible that a game changed the scale and was shut down before changing it back.
Had found similar possible solution elsewhere and tried this but retried just now and when I rightclick, nothing happens. Again nothing changed, fully reinstalled the app itself since I was told that could solve it. But didn't, it's something in the pc. All graphic settings to recommended, nothing special there. Recently did an update to nvidia drivers, maybe that or otherwise something that updated in relation to xbox app and microsoft store perhaps?
