My Main Unity Project Crashes on Startup, Access Violation

Hello! I have tried googling everything I could think of, still haven’t found an answer to my problem.

First of all, this wasn’t happening yesterday and I have been working on this for months. I didn’t make any changes in scripting, just messed with a particle system and when I closed untiy, then tried to reopen, I got the normal launch screen. When I clicked on my project, it opens a white screen for a few seconds, then opens the unity crash report window. Only this project does it, no other project has a problem opening. I have looked at the logs (Editor log and crash log) and this is what they say:

Editor.log stacktrace:

error.log error part:

If you need more information, please let me know! I would love to know what I can do to fix this. Thanks in advance :slight_smile:

Well I finally found this: Getting the Unity Editor to Work in Windows 7 64-Bit - Questions & Answers - Unity Discussions

And it seemed to have fixed it so far! Hopefully that was a permanent fix!
