Charmap.exe process being killed?

Question

I do not think this is an Adobe issue. I think this is a Windows issue or maybe an anti-virus issue.
 
When I try to use the Insert > Character > Character palette to insert special characters, the window is closed before I can do anything. Thanks to an old thread revived by Klaus Daube, which identified Charmap.exe as "an add-on unicode entry tool", I decided to use Task Manager to see what was happening with that executable.
 
Sure enough, when I try to use the Character Palette, the Charmap.exe is added to the list of running processes. And then it's removed. Something on Windows is killing this process. If I can figure out what it might be, I might regain the in-program ability to insert special characters.
 
Anyone have ideas on what might be killing this process?
 Windows 10, 10.0.17763.0
FrameMaker 2019, 15.0.4.751
(Windows updates are controlled by the IT department; there's nothing I can do about removing an update or getting it to update to the most recent patches.)

I reported this issue to my company's tech support, who then brought Adobe support in. What I'm being told is that Adobe is working on a fix for this but there's no ETA.

Yay? I mean, glad that someone has apparently figured out the cause and that a fix may be provided. Still love to know what the cause is, because that's the sort of person I am. And honestly, really surprised that it isn't thanks to an over-eager anti-virus or something like that.
