Hello,
The only way to recover will probably be to delete the entire data directory for the itch.io app. You'll have to log into the app again, and update any settings that you may have set. From the error that you pasted, it looks like the directory is at "C:\Users\Alia\AppData\Local\itch"
If you're worried about deleting it and losing information, you can rename the folder to something else and try starting up the app. Make sure the app is fully closed and not running before you rename or delete the directory.
Thanks
