Describe your issue

System's %PATH% is overwrite, micromamba for windows,

In file _mamba_activate.bat, when @CALL "%_TEMP_SCRIPT_PATH%" is executed, System %PATH% is overwrite. so system's command can't be found.

I made temporary modifications to facilitate correct usage :

@SET OLD_PATH=%PATH%

@CALL "%_TEMP_SCRIPT_PATH%"

@SET PATH=%PATH%;%OLD_PATH%

same for me: when I activate an environment, it it now overwriting my path instead of appending to it. This worked fine for me before updating mamba 2.0.0

The problem has been addressed in mamba 2.0.2, can you confirm it fixes your issue?
