Thunderbird crash when attaching any file in file picker

I have Windows 10. I am using Bitdefender. Thunderbird 128.2.3 est (64 bit).

When I attach a file to an email, Thunderbird crashes. This happens eventhough the file is well below the maximum allowed.

Up to approx. two weeks ago when it happened I could just restart and it would work. Since last week it does not work at all. It will not accept any attachment.
