powershell windows-7 crash powershell-ise

Not sure why, but today my workstation refuses to load the Powershell ISE. I can load Powershell just fine and my cmdlets work. I've tried loading both the 32bit and 64bit ISEs and both crash for the same reason.

This is the crashdump:

I couldn't find anything on google on this crash so I'm hoping someone here has some guidance.

This may be completely unrelated but in my case, I didn't understand much when I looked through Process Monitor to determine what was causing the crash as a windows update (cherry picked by our Helpdesk team), broke my PowerShell ISE launch, I also tried running without a profile. with Powershell_ISE -NoProfile

I followed the techcommunity thread and was able to fix my issue with Solution #3 GlobalUserInterface.CompositeFont from dotnet github issue

All I had to do was download this font and update it at below locations, PowerShell ISE is a WPF Application and Fonts were corrupted by dotnet upgrade as a part of KB4074906

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\WPF\Fonts and C:\Windows\Microsoft.NET\Framework\v4.0.30319\WPF\Fonts
