Can't handshake with SuperCollider without control port

Hey,
I am trying to get started with TidalCycles, but there is no sound, and instead there is this error message.

I am pretty new to everything, so there is also a possibility that I didn't do something very obvious that is needed. Help is much appreciated!

I am using Windows10:-)

t> [TidalCycles version 1.8.0] Installed in C:\Users\vivien\AppData\Roaming\cabal\x86_64-windows-ghc-9.2.3\tidal-1.8.0 Listening for external controls on 127.0.0.1:6010 That port isn't available, perhaps another Tidal instance is already listening on that port?

t> Can't handshake with SuperCollider without control port.

Thank you!!
