Quelea 2021.0 crashing after Mac Monterey upgrade

After upgrading MacOS to Monterey, Quelea has become very unstable. If it fully launches it can crash after importing a song, bible adding a song to a schedule, opening a schedule or saving one, going live etc. All very random, but now unusable.
Crash log below was created whilst trying to import a song pack (character limit meant only first part of log attached).

Afraid this looks to be a crash deep within the JVM itself, so unlikely to be an issue in the Quelea code directly. Have you tried the 2022.0 beta release, and does that make any difference?

sadly no, for the 2022 beta, whilst better, still crashes out when you try an do something like add a bible, edit a song (typically on save) or even just add a song to a schedule. Tried completely removing Quelea (including from library etc) and reinstalling but to no avail.
