`rasterize=True` thorws `RuntimeError: no running event loop`

Hmmn I don’t get this traceback you have. If you work with the virtual environments I’d spin a new one up with just hvplot pandas etc as you may have some incompatibility issue going on with something else…

I just noted looks like your using mamba for installation? I’m sure it works but i did have various issues with it myself on a windows machine so i stuck with mini conda which I had more success with
