Can't change list and menu fonts in Thunderbird v 115.5.0

There is a long thread about problems with changing font sizes in recent earlier versions of Thunderbird but until yesterday, I never had the problem.     I periodically have to enlarge the scale of fonts etc., in Windows 11 in order to read file lists in Windows Explorer. When I do that, the menu and list fonts in Thunderbird appear very large.  So, I go to View > Font Size and reduce the font size or simply reset it.  After I finish my other task, I simply reduce the font size again.      

 

But last night the function stopped working.  I tried just about every fix recommended here or elsewhere.  No luck.  I updated to v 115.50.  No change.   

Any new thoughts? My 80 year old eyes can barely see what's on the screen.  I have been using Thunderbird forever, it seems.  

Thanks.
