I’m unable to launch MSFS (probably since last windows update). It was running well until today.
I completely uninstalled the game and reinstalled it (from steam) and when I launch MSFS no window is opening.
My graphic card drivers are up to date (Nvidia v 555.99)
My last windows update is KB5039212
In the systemps logs I have those ones :

If fault persists, load XBox App, my library, select FS2020, top right, grey box, three dots, press. Select Manage, select Files, select Verify and Repair (you may need to try and run FS)
Reboot PC
Try FS - still a problem, carry out a repair of Windows
I tried all of them and I still get the same windows error at startup
I also tried to reinstall Steam, MSFS, VisualC++ Redistribuable, My Graphic card drivers.
I also Uninstalled+Reinstalled the latest windows update…
From the windows events it seems that the error is linked to ucrtbase.dll but I don’t find any interesting post about it.
I don’t know if this will resolve your problem, but I saw a recent video stating that the NVidia 555.99 driver had multiple issues. Since you’re kind of out of options at this point short of a rebuild, you might want to back off that version and see if that helps. Good luck.
