If this is in CMD, can you try calling CALL micromamba ... instead?

[CDTR-MattConroy]

Thanks @jaimergp that fixed it. Is there any reason why this needs to be the case? I find this somewhat surprising and unexpected?

[jaimergp]

There's a similar bug report in the conda/conda repo (sorry I'm on my phone and can't link). I assume it has to do with the shell integration using exit without /b somewhere.
