I can't reproduce this.

Does this also happen in safe mode? https://support.mozilla.org/en-US/kb/safe-mode-thunderbird

(It is good to test safe mode before filing a bug report, and mention it in the bug report)

I am using Bit Defender. And I just saw several posts about its "add-on" maybe causing the problem.
Just switched it off and that solved the problem. I do find it odd that the problem JUST started with the newest Thunderbird download.
One of those things, I guess. Thank you for the suggestion (question) that led to the solution. Much appreciated.
