LO writer: insert special characters fatal errror LO

I’ve read that a bug was fixed that caused a fatal error. But I’m still getting a fatal error crash when I attempt to insert a special character.
Windows 10 OS, on Intel 64 platform

I found that when I changed font to Arial Black, and used the “Special Character” button, it just freezes the program, rather than stating “Fatal Error,” and crashing. This problem seems to have been around as a question for a long time. It’s surprising that it hasn’t been resolved yet. (I used “Insert” and special character the first time, when it crashed.)
