Windows 10: .NET Apps stop working after installation of KB4569745

Greetings,
My event viewer Windows Application log has several entries like this, all with a faulting module of clr.dll:

Faulting application name: powershell.exe, version: 10.0.19041.1, time stamp: 0x30f12f73
Faulting module name: clr.dll, version: 4.8.4200.0, time stamp: 0x5ee03350
Exception code: 0xc0000005
Fault offset: 0x004fb86c
Faulting process id: 0x51f0
Faulting application start time: 0x01d671fb01c2ad7b
Faulting application path: C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe
Faulting module path: C:\Windows\Microsoft.NET\Framework\v4.0.30319\clr.dll


Lots of programs have stopped working Quickbooks, Grammarly Add-in for Office, Gigabyte Mobo Utilities. Uninstalling KB4569745 removes the problems/errors. Everything else on the computer seems to be running fine.

Anybody experiencing anything similar?

:)
