                OS: Linux

Impossible to start Thunderbirdportable.exe  (78.3.2 portable 64bits version)
with wine 5.22-1 while it worked fine with the previous version 5.21-1. I had
to downgrade to wine 5.21-1 on 3 different computers, under Archlinux and
Manjaro. 
It still works with an old x32 version of Portable Thunderbird. Is this bug due
to wine64 ?
