@Hester40MT - many thanks, this is the first tangible lead I’ve got after doing tons of things and researching it as well.
So, if I understand correctly, this is what I need to do
- Completely uninstall MSFS
- Format F drive that holds current packages for removing all WpSystem files
- Change the location of Windows store back to C drive
- Reinstall MSFS - this time still selecting F:\MSFS for core packages install (Community & Official folders)
And hope it works
