Updated to latest Plastic version but does not connect to Unity Editor

Hi, I am new to version control systems and fairly new to Unity, any help appreciated.

Unity Editor v.2021.1.28f1
Plastic SCM Cloud 11.0.16.7778
macOS 13.0.1

Thread with the same issue unsolved in 2022 in the Plastic SCM forum Updated to latest Plastic version and Unity no longer connects within the editor - Unity 3D - Plastic SCM Community

Have a Project using Plastic SCM Cloud but after updating to Plastic latest version 11.0.16.7778 (since i was 12 versions behind) the Unity Editor gives now an error in Project Settings >Version control after selecting mode: Plastic SCM , saying is not connected to Plastic. Version Control Plugin Error

and on the Editor’s window bottom : Version Control: UpdateSettings: Plastic SCM not installed.


Question 1:
Can i try and uninstall the Version Control package to see if fixes the problem, and be sure the project’s workfolder won’t be affected/deleted?

Question 2
is it a must to set Version Control mode to Plastic SCM in Project Settings?
because i have other project using Plastic (connected to Plastic before the update) working fine but Project Settings >Version control mode: Visible MetaFIles

Thanks!

You can uninstall the package via Package Manager, but it will not help because this error is from the legacy Plastic SCM integration. See more info below.

No, in fact, please do not set this and leave it with the default value. This is the legacy Plastic SCM integration that was superseded by the Version Control package installed via the Package Manager.

Hope this helps!
