I am currently on Windows 11 and facing this problem since upgrade. Each time I install anaconda-navigator, on first time opening it runs smoothly however on second time if I open from windows, it opens but gets stuck on environment loading and when I open it from prompt, I get the error below. I do realize that error is from conda-script.py line587 however I don't want to do modifications blindly so need some expert opinion on how to resolve it. I never faced these issues even on last moment on Windows 10, and I don't know how much windows upgrade is a problem here.
