Every time I launch PowerShell ISE (x64 or x86), I get this:
It is drawn exactly as shown and immediately unresponsive. The black part at the bottom is within the window boundaries.
PowerShell CLI runs just fine.
I see nothing in Event Viewer apart from a record of the app hanging when I attempt to close it.
I tried downloading the GlobalUserInterface.CompositeFont font as part of Solution #3 at this issue, but the download link appears to be broken.
I have no pending Windows Updates as of this post. I am running Windows 10 Pro 21H2.
How do I figure out what's going on?
EDIT (2021-01-02T03:32Z): Apparently it's just taking forever to start up. It eventually rendered, 10 minutes later. If Visual Studio 2022 can open in less than 10 seconds, PS ISE has no excuse. What in the heck is going on?
