Thanks, after removing the venv the message comes, that python 3.11 gets activated and comes a warning for incompatibility.
I have activated systemwide python 3.10 with a virtual environment with conda. And even in the stable diffusion folder it is set to 3.10
Is there a way to install or force for the stable-diffusion-webui.bat a python version? I have testet “set PYTHON =3.10” in the bat but this gives an error for unknown command.
