Cannot start Bisq 2 on Whonix WS

Hello,

I installed Bisq 2 on my Whonix Workstation as described in the official documentation on the whonix wiki.
I am unable to run it. I get the error messages:
Warning, Initialiasing applicationService failed.

And
An error occurred at initializing Bisq: bisq.tor.controller.TorCommandFilteredException.

Is there a known fix for that problem?

Kind regards
