Please help! Function Edit - subsequence (and features) not working

[avonm]

Hi,

I love Artemis and I need to to work!
Please advice me to fix this error.

I have installed artemis both via terminal and also by downloading the dmg.
I've tried JDK 19 and JDK 21 (the latest version).

It runs but when trying to use Edit -> subsequence (and features) it freezes and nothing happens. I suspect it has something to do with Java. Otherwise it seems as if artemis is working fine.

This is whats prompted in the terminal:
art
Starting Artemis with arguments: -mx2g -ms100m -noverify --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED -Djdbc.drivers=org.postgresql.Driver -Dartemis.environment=UNIX -Dapple.laf.useScreenMenuBar=true -Xdock:name=Artemis
Warning: the fonts "Times" and "Times" are not available for the Java logical font "Serif", which may have unexpected appearance or behavior. Re-enable the "Times" font to remove this warning.
