Hi Christian,
in fact I installed BaseX from the .exe. I did now try the .jar and .zip and those work without any problems. Then I did a clean reinstall with the .exe and this seems to have fixed the problem. This is the first time I had problems with installing a new version over an existing installation.
For what it’s worth, when starting the jar-file from the .exe before the reinstall and clicking on the icon I got in the command line:
