I have unsuccessfully followed to the best of my ability the instructions located here for migrating the Thunderbird profile folder to a new PC: https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer (my new operating system is Windows 11 Pro). The folders appear to be installed on the new PC when I examine them through File Explorer, but they don't load into Thunderbird when I open the app.

I read somewhere in one of the comments to this article that it is critical that the versions of Thunderbird on both the old PC and the new PC must be the same. But am confounded as to how to do that. When I look for updates to the version on the old PC, I am offered version 115.10.1. But when I try to download Thunderbird for installation on the new computer, one is only offered 128.3.1esr. How, may I ask, can one synchronize the versions of Thunderbird on both computers then? Where can I find an older version of Thunderbird to download onto the new PC? Or get the version of Thunderbird on the old PC to update to the latest release?
