How to configure bspwm in WSL2 Ubuntu?

I'm trying to install bspwm in WSL2 Ubuntu-24.04 LTS, and each time I run bspwm, it says "Another window manager is already running", and I don't have any other window manager installed. What is the problem? xclock runs alright. Does that mean that WSL does not support bspwm? I am completely new to linux and I canot find any guide about installing bspwm on WSL.
