WSL - KEX - Unable to connect to Socket (10061)

Hi,

After installing Win-Kex I tested to start KEX and everything was OK.
But I made the mistake to Log off the Linux session in the UI.

Now I cannot connect using TigerVNC Viewer.
The error message is both in English and Swedish (Since my OS is Swedish) but basically says this: Unable to connect to Socket (10061)
I've tried to shutdown WSL using WSL --shutdown, but that didn't help.

I'm a Linux newbie so the answer is probably easy, but I can't find it.
Anyone?
