On 8/15/22 Thunderbird suddenly reverted back to v91 and prompted to create the first email account. There was no access to pre-existing email accounts. It was as if Thunderbird had been installed for the very first time. This happened on my computer and several of my customers' computers running Windows 8.1, and Windows 10.

We ran antivrius scans on all computers and found no malware.

The solution was to reinstall Thunderbird v102.1.2.

Anyone know why this is happening?

Thunderbird would not on it's own reinstall and older version. I would suspect some AV or software management software on your PC caused the downgrade.
