Can not go to Main Menu from MSFS2020

I installed MSFS2020 on a different drive (my case H) and most everything seems to be working properly (tokens are on the C drive that direct to H drive) but the problem I’m now having is that when I want to load in another airplane or location and I try to go to MSFS main menu the program shuts down to the desktop and I have to reload the whole program again.

If I want to just restart the flight that I’m already in - no problem, the return to the main menu of MSFS2020 ends the program.

Any ideas?
