Issue

I spent Friday repeatedly rolling back my workstation miniforge installation because I could no longer use conda in powershell. Eventually I noticed that Powershell 5.1 shipped with Windows was working normally. I ended up with two command prompts side-by-side, entering powershell -noprofile and pwsh -noprofile, then loading each of the files specific to the PS5.1 $PROFILE variable into both terminals, one-by-one. This resulted in a working PS5.1 prompt and a broken PS7.5 prompt.

Looks like they bumped a version on the .NET SDK. Here's two relevant links:

Confirmed behavior using my home computer now and a workstation on Friday.

This is a bug in conda, and it was fixed in version 25.1.1 (conda/conda#14292). Unfortunately, the conda version included with the current miniforge does not have this fix. We can manually update the conda version built into miniforge by using the following commands in the Miniforge Prompt, and then rerun conda init.

conda install -n base conda=25.1.1 -c conda-forge --override-channels --yes
conda init --reverse
conda init

You can try https://github.com/conda-forge/miniforge/releases/tag/25.3.0-1

(sorry i can't help troubleshoot, i don't know how to use windows tools)
