Latest ThunLatederbird lost several folders and says the ones that show are empty. I tried INBOX repair and now all folders are empty and others still missing.

I am using Thunderbird 140.10.0esr (64-bit) (latest) and for some time I have had a lot of trouble with it moving folders out of alphabetical order (but not all folders) and when I tried to move them where they belong it complains. Then today it can not find several folders. I can not even see the *.msf files and yet the utility "EVERYTHING" says the msf files are in the default directory where they belong but they are not visible from Windows 10 explorer and Thunderbird is not telling me that all folders are empty (including inbox). How do I repair Thunderbird? HELP!!!!!
