Suddenly Thunderbird won't start

Thunderbird won't start. The framework is there, but "No message found" is displayed and TB is not responding. So I did a backup copy of the current profile, then downloaded and installed (with "Upgrade") 128.7.1esr.exe But the result is the same. What next?

This may have been due to an automatic upgrade to my Windows 11? See attached image.
