MSFS Won't Start/Launch

I opened the PC to get SU12. Downloaded the latest GPU and Windows Update beforehand just to make sure everything is clean.

Tried launching the app and nothing happens, no pop up, no splash screen, no error, absolutely nothing. I usually launched through Addons Linker and nothing happens. Tried launching as Administrator straight from search bar, nothing happens.
I redownloaded the xbox app and rest gaming services, still nothing.
I’ve spent all day trawling fixes and nothing seems to work. xbox app shows game is installed, I haven’t deleted anything.
I didn’t want to post here without exhausting every avenue.
Has anyone got any ideas that I may try. This has never happened before and I doubt its linked to the initial updates I did.

Thanks in advance
