One more thing, I don't know what is occlusion culling. If it's a script, delete that script then try to open it. If it's not a script, I don't know what to do know.

My project crashed once and cannot be opened again. What worked for me was to open that project on different computer, export the package and the re-import the package in the computer that was crashed.

Hope this works for you too.

OK Guys, What is happening is after a crash, the scripts that have caused your crash or contributed to it can't compile upon restart. follow these step to fix it.

  1. Make a backup

  2. remove your scripts folder

  3. open your project.

  4. re-import your scripts folder.

  5. apply the scripts back to where they were.

  6. save project and scene

If that doesn't work: reinstall unity then follow steps.

I've had the same problem and what I've made is delete all *.meta files in "Assets" folder in my project. Unity had to import all assets again and the project still works good :)

You can also delete the last added script from assets and try to import it again. Maybe it would help.

I just stumbled on this issue and I paniced a bit. After reading this I realized something was probably off with some new folders and managed to fix it by cutting out the foldername with the issue. Somehow one foldername would never load. Probably some metadata lost in oblivion. I tried after being able to open unity again, I tried creating a new folder with the same name that initially had the problem and instantiating objects from it. But it never worked. Creating a new folder with a different name made everything work again. Scary business. Always do backups!
