Redeploying an environment fails?

I had an environment set up for Python that was using the wrong version (3.8.3 instead of 3.7.7). I tried to redeploy the env to the new Python tag, but the process just spun out. I couldn’t find a way to cancel the job and ended up creating a new environment from scratch. Has anyone else seen a similar issue?

Ok, as soon as I posted this, the process finished after 10 minutes. Most environments have spun up in ~1 minute, so I’m surprised this took so long.
