Issue

After installed the latest miniforge, running mamba init powershell, but the mamba activate/deactivate is not working. It will not change the env and output no errors. And conda activate/deactivate is working properly.

I have the same issue, and it does work in Windows Subsystem for Linux.

in Powershell:

> cd C:\
(base) PS C:\> where.exe python.exe
C:\Users\Matthijs.Kramer\AppData\Local\miniforge3\python.exe
C:\Users\Matthijs.Kramer\AppData\Local\Microsoft\WindowsApps\python.exe

In WSL (Ubuntu terminal):

I have the same issue. mamba activate/deactivate works in cmd but not in PowerShell.

[rubenmejiac]

I have the same issue using Windows Powershell and Powershell 7.
Using command prompt, using the Miniforge3 prompt shortcut, everything works as expected.

Adding "help wanted" as this will need code contributions from someone familiar with and the ability to test Windows and PowerShell to improve
