What happened
When you are trying to create project with existent on the web site name then you will get error in Connect window

How we can reproduce it
1 it is happens on both Staging and Production
2 you need to have project with some name e.g. "New Unity Project" on the services web site
3 create in Editor project with name "New Unity Project" and make sure that in launcher window "Enable Unity Analytics: is turned on (see attached image step3)

Actual result: when Editor will be opened - the "422" error will appear in Connect window (because we already have project with this name on the web site) - please see attached images
Expected result: probably we can handle that error to not show it to the user (not very good to show "bug red error" on creating new project...)
