2017.3.0f1 Missing UI dll

I just installed 2017.3.0f1 and I seem to be missing the UI dll. I started a project by importing Zenject, UniRx, ProBuilder, and Odin Inspector, but I immediately get a bunch of compiler errors saying I'm missing types from the UnityEngine.UI.dll

I'm on Ubuntu 17.10

 

Quick update, I wasn't really able to fix it but what I did was create the project in 2017.2.0.f3 with those same plugins and then I opened it in 2017.3.0f1 and it seems to have worked fine. I'll post if there's any other update

 

ive been getting around it by running as root, and then vscode in root to debug. the editor crashes all the time for me, and i assume its because I am root. But I was able to jam a small game to completion this way by saving often

edit:
after playing around with it, i found that it didnt give have the proper permissions for me. try "chown -r youruser.yourgroup Unity-2017.3.0f1"

 

That seems to have done the trick. Thanks!
