Unity Quitting Unexpectedly when opening certain projects but not all projects

I am trying to open a project that I pulled from my git server. Unfortunately, Unity quits unexpectedly when trying to open the project. However, it will open my projects that were never committed. How do I open my project that I pulled from the git server?

This is the what Unity gives me in my problem details:
