UE-4.27.1 Crash on exit.

UE-4.27.1 crashes on exit trying to illegally access address 0x0000000000000024. It does this no matter what project I open. Even blank ones. Started doing this on release of UE-4.27.1. Tried uninstalling several times. No luck. It does not seem to affect the project, but UE-4.27.1 is broken.

Was forced to pick a tag that does not apply.
