"PlasticSCM does not exist in the namespace 'Unity"

I updated my project from Unity 2020.3.15 to Unity 2020.3.20f1 and then the console shows this error:

I tried re-importing the assets. Then regenerate project files. Went back to 2020.3.15, having the same error, then going back to 2020.3.20f1 and still the same. I uninstalled all unity editors and unity hub, restart my pc and then installing them again, but it still shows the same error. I thought it may be the project and I tried creating another one but it isn’t the case.

Do you use either Collaborate or PlasticSCM with Unity editor? If not, just uninstall the Collaborate / Version Control package. Otherwise try to update it to the latest version.

No, I don’t use it and I didn’t know about that. Thanks, removing it worked.

You should however consider using proper industrial-grade source control in order to guard and protect your hard-earned work.

Personally I use git (completely outside of Unity) because it is free and there are tons of tutorials out there to help you set it up as well as free places to host your repo (BitBucket, Github, Gitlab, etc.).

You can also push git repositories to other drives: thumb drives, USB drives, network drives, etc., effectively putting a complete copy of the repository there.

As far as configuring Unity to play nice with git, keep this in mind:

It is only simple economics that you must expend as much effort into backing it up as you feel the work is worth in the first place.

Thank you! I already use a source control outside of Unity, though I found your posts worth checking out and learning more about source control and git.
