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?

This review is for a previous version of the add-on (5.11).  This user has a previous review of this add-on.

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.
