Unity Opening Two Windows (And other bugs)

When I open my project, it opens 2 windows (see picture). It doesn’t allow me to pull up this second window. Also, sometimes after I exit play mode, it pulls up the second window, and doesn’t allow me to pull up the project, unfortunately, I was unable to recreate this.

I have been having many problems with this new version of unity, including having to reinstall unity just to be able to open scripts, actions taking forever to process, and popups taking 12-15 minutes to disappear. These bugs are making it close to impossible to work. And it seems to be getting worse with the new versions.

I use Unity 2020.2.1f1 no problems

I’m on 2020.2.0f1 and I have the same issue.

Have you found any solutions?

No… it’s affecting multiple people on my team. Started happening when we upgraded from 2020.1 to 2020.2.

I’ll probably submit a bug report soon.

Are you using the collaboration package by any chance?

Nope. I’m using PlasticSCM as version control system, and Cache Server v2.

I’ve heard that the collaboration package is automatically on, and causes problems. I’m going to turn it off and get back to you.

Didnt work . . . Does it work for you?

Have you tried going to Window → Layouts → Reset all layouts? Looks like it sort of fixed it for me, at least temporarily.

This is what I get, only lets me quit Unity. I can assure you I have no compile errors in my project, however I do have the ProBuilder window and the ProGrids window open.

Ahh . . . Great, I can no longer open the project. Can someone from Unity please help? @SteenLund

THANK YOU! That fixed the issue completely. Until the next error that will give me a heart attack . . .

why is the first comment ALWAYS some fanboy instead of just a useful answer.
