There is a quite similiar issue already on the bug tracker:

But as i can see in the log, you already using the described workaround with -Djdk.gtk.version=2. :see_no_evil:

With the same instructions given in the github issue, you can add the option -Djdk.gtk.verbose=true and see what GTK version is used (2 or 3).

Otherwise, maybe the setting GDK backend to x11 described here can help.

Nope. According to the log file -Djdk.gtk.version=2 has been passed as a program argument to Cryptomator, not to the JVM:

Received launch args: -Djdk.gtk.version=2

In order to be effective, it must be added to the cfg file as described in your link.
