I updated to Pro 2.2.0 today and noticed the default python environment is now read-only. The previously downloaded packages I had were wiped out with the new update. I need to get the package, spyder, back into my environment. So, I cloned the arcgispro-py3 environment in order to make the install. 
Notice that the window says, "Restart ArcGIS Pro for your environment changes to take effect."
So, I clicked 'Exit'.
After the program restarted, I no longer have a cloned environment to select.
Can someone please help?
Your potential update is quite significant. I have Spyder installed as my python IDE so that accounts for only a few of your upgrades and the ArcGIS accounts for some more.

What are you using for python?
I wouldn't install via pip let conda manage things.
You could give it a go, but I would have the ArcGIS pro install *.exe or at least the *.msi and *.cab file on hand incase you have to do a complete reinstall 
You might want to start a new thread if you have issues..
took a few tries but ....
