Processing-4.0b2 crashes on Fedora 35

on my Fedora 35, processing-4.0b2 crashes any time I try to open a file.
When I launch from command line, I get:

[-----@localhost processing-4.0b2]$ /home/-----/processing-4.0b2/processing

Do i need to post hs_err_pid759383.log somewhere?
Let me know, I am not sure whether it is a Processing issue (what adaption is?)

Note, processing-3.5.4 works fine on the same machine.

processing-4.0b3 works fine. Issue closed! :slight_smile:
