Closed as duplicate of #19044.
I've known about this issue for awhile. I just haven't found a way to get it working with OpenWebStart.

As a workaround, you can either use Oracle Java 8 (I don't recommend this) or use the .jar file downloaded from the website with Java 11+.

Sorry about this,
Taylor
