SuperDirt error – Server 'localhost' exited with exit code 0 (solved)

Hello,
I am on OSX 10.13.6. After quite a few attempts I was able to install the Tidal library via cabal v1-install tidal (thanks to the troubleshooting section in the Documentation).

At some point, when Tidal was still not installing, I had Superdirt running (SuperDirt: listening to Tidal on port 57120)

Now, I only get

-> SuperDirt
Booting server 'localhost' on address 127.0.0.1:57110.
Server 'localhost' exited with exit code 0.

I only have the Xcode command line tools installed at the moment. I am just mentioning it, because I think I might have had Xcode still installed when SuperDirt worked. Does ist matter at all?

Any pointers would be much appreciated... Thanks!!!

I have uninstalled SuperCollider and all extenstions, quarks etc. and after a fresh install it seems to work.
