Hello,

I set Anaconda up months ago and it was working. Tried to fire it up today and I’m getting a red error popup with the following text:

_startServer error: Command failed with exit code 1: “C:\Users\kapla\AppData\Local\Programs\ai-navigator\resources\micromamba.exe” --no-rc --no-env --root-prefix “C:\Users\kapla.ai-navigator\micromamba\envs” create --json --yes -p “C:\Users\kapla.ai-navigator\micromamba\envs\cpu\_v1” -f “C:\Users\kapla\AppData\Local\Programs\ai-navigator\resources\assets\environments\cpu\_v1.yml”_

Any tips?
