Powershell ISE stopped working prompt

So not sure if it related to Patch Tuesday or not, but after I updated my computer Powershell ISE stop working.
I have search the internet for fixes and tried them.
  1. MalwareBytes for Poweliks and nothing came up
  2. Installed PS 5.1
  3. Checked and confirmed that KB3163245 is installed, but this was well before I started to have this issue. I did uninstall it, but still having the same issue.

Any Ideas

Anything in the Application Event logs related to the exception?  Same problem launching x86 and x64 versions?  As admin?

A side note, but I ditched ISE for Visual Studio Code as I found the interface, bug testing, and other features to be much more useful.

Nothing that helps.
I did do a system restore to the right before the updates applied and I was able to access ISE, but one the updates pushed again it stopped working again.  This is leading me to believe that one of the recent updates.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

And, what OS are you on?
yo_beeDirector of Information TechnologyAuthor Commented:
Found the culprit.
Update for Microsoft .Net Framework 4.7.1 (KB4055002)
I uninstalled this and  Powershell ISE worked again.

Dustin SaundersDirector of OperationsCommented:
Doesn't look like they have a workaround to that problem other than what you did there, but they do have the Security Only patch which suggest as the alternative.

yo_beeDirector of Information TechnologyAuthor Commented:
That was not the one I removed.  That one did install and actually is not listed in the updates that I can uninstall.
