MSFS Crashing, Event Viewer, ucrtbase.dll

Hi all!

Out of random with no warning, the sim starts to lag then freezes the entire computer. The seconds on the clock doesn’t move and can’t move the mouse anywhere. The sim crashes and the computer goes back to normal. Any idea on how to fix?

Found this in event viewer, hoping I could get an answer.

PC specs:

  • 13th Gen Intel(R) Core™ i7-13700K 3.40 GHz
  • NVIDIA RTX 4070ti
  • 32 GB of Ram
  • Windows 11 Pro 23H2
  • ASRock Z790 Steel Legend WiFi

All help appreciated!

Hello @techdude1610,

Have read of this support guide about the DLL error you are receiving:

Open a command prompt with admin rights…

Go through each of the following steps one at a time. Copy each line, one at a time , paste it into the Dos window (crtl + V) and press return

and it will then run. Wait until each runs and finishes before you move on to the next one.

When you are completely finished, Restart your computer and then try to see in MS2020 will start and run properly

Dism.exe /online /Cleanup-Image /checkhealth

Dism.exe /online /Cleanup-Image /scanhealth

Dism.exe /online /Cleanup-Image /Restorehealth

sfc /scannow

Dism.exe /Online /Cleanup-Image /AnalyzeComponentStore

Dism.exe /Online /Cleanup-Image /StartComponentCleanup

RESTART your computer as the last step. Then go for a test flight.

Hope above posts can help.
