The freeze occurred after update to 5.11, and prior updates. There are no freezes during normal operation (no updates).
Is there better way to report problems?

Yes there is - on the QuickFolders github:

When you report an issue like this, it is important to know which version of Thunderbird you are running. Thunderbird 102 made a change to servernames that can potentially invalidate all tabs in QF and it tries to repair these based on the previously stored account. Apart from that, 5.11 actually does a lot _less_ then the previous versions so it should run quite a bit faster than 5.10.3 especially on Thunderbird 102.

Edit: no need to leave 2 reviews, you can also reach out directly to me via the support tab in QuickFolders settings - I usually reply on the same day.

Nice addon. However, recent updates will freeze Thunderbird when a new tab appears with a change log and donation requests. Must terminate Tbird via task manager.

thank you for your feedback! If you are running Thunderbird , 102, please try version 5.11 it addresses a lot of the performance issues that were recently introduced. Generally Thunderbird does take quite a longer when we have many folders in the tree, so there will be more scope for improvement. Especially starting Thunderbird and installing a new version of the Add-on can lead to some unique delays that may coincidentally make it seem the history is slowing things down - but it is actually the initialization of the folder tree, which is currently a little inefficient in Tb102.
