Exit Unity. Delete Packages folder in your project. Reopen your project. Problem Solved.

Same here. Unity 2017.3.1f1. Windows 10.
I had been using a One Drive folder as the project folder without issues for some weeks. Then after a re-install of 2017.3.1f1, I found that Unity almost always crashes on startup unless I (1) kill OneDrive and (2) delete the UnityPackageManager folder from the project folder. Then it will always start successfully. I can restart OneDrive immediately after Unity launches and have no problems while working.

My Unity version was also crashing with the Package Manager while "resolving packages". Running Unity as administrator fixed all my problems!!!

Moving files locally fixes the issue for now. However, this is not ideal as I work on this project from multiple PCs (Not at the same time of course)

Looking in to the OBEREON sugestion above, I stumbed in to this...
I have two computers, one at work and other at home.
But the usernames are different, hence, they are not the same in the csproj files.
And the project opens here at my work computer, since the path matches with the csproj file. Need to test in my house later today.

I was able to correct the issue by removing drive references from the csproj files - change c:/x/ to x/
The root cause appeared to be the inability to find the necessary assets and packages due to the change in drive letter and the use of absolute paths.
