Windows 10: Your Trial Period has Expired & This App Can't Open

I can't open basically all my games. Forza Horizon 3 & 4, your trial period has expired. This has happened once before, I own the game, last time the error 'Check the Store for more info about Forza Horizon 3.' and 'Get help with this' that just opens the Microsoft Store and has a reinstall button. I can't reinstall the games again, FH3 is 60GB and 4 is 90GB or so. Only Among Us & FH5 work. Asphalt 8, 9 and all my other apps that aren't games wouldn't open apart from system apps, e.g. Settings with This app can't open. Can anyone fix this issue? I even have an offline copy, an EAppX,

What makes Windows 10 know a trial period for an app has expired?

I've looked at this in the past and found that some apps create a registry entry on first use that holds a hash of the date and time of use. This key is not deleted on uninstall.

Being a hash it's impossible to modify it without making it invalid (which the app treated as 'trial period expired'). In some cases deleting the key would reset the app to 'trial period not started yet'. It's of no relevance to me now, I have since found other ways to do the same function with software that doesn't expire.
