Simulator doesn't start anymore at all

I’ve checked windows updates and nothing pending at all. Version is 20H2 (Build 19042.685)

I’ve then uninstalled all graphics drivers and done a clean install of NVidia for my 2080TI. Just tried to launch and same problem as before (blue bar freezing on black screen.

On event viewer, the only red errors I have recently are as follows

  • 65 “Failed with 0x57 retrieving AppModel Runtime status for package Windows.”
    -18 “The Windows Security Center Service was unable to load instances of FirewallProduct from datastore.”
  • 2 “Session “PerfDiag Logger” failed to start with the following error: 0xC0000035”

Would any of these be related to MSFS? I always launch via Microsoft Store
