e[31merrore[39m:   Unexpected error during IPC communication:

I’d try the following:

  • Can you still open another project or create a new project?
  • Maybe try deleting the Library folder.
  • Do you have source control? Can you rollback the project?
  • If you don’t have source control and deleting the library folder doesn’t work then it might be worth making a new project and transferring the files over to it.

Can you still open another project or create a new project?

  • I can create a new project. If I open a script from the explorer and create a error I am also able to open the project in safe mode and normal mode. But there is no other errors. Have recreated the project multiply times as well.

Maybe try deleting the Library folder.

  • Have done this, had no effect.

Do you have source control? Can you rollback the project?
If you don’t have source control and deleting the library folder doesn’t work then it might be worth making a new project and transferring the files over to it.

  • Don’t have source control. I have copied to a new project the moment I try and open my game scene it crashes.

Strange, I haven’t had this issue before in the past. It does mention something about a IPC error. This post says that Unity wont work with a network shared folder. Unity Hub does not Launch (Critical Error Encountered) v 3.0.1 2022 (Manually Solved)

Looks like you’re already using the latest version of Unity. Maybe try upgrading UnityHub. You might have to try gradually moving parts of your project over to a new project to find where it breaks. I’m guessing it’s not related to your c# code. Maybe it’s from a third party package. Was this project maybe upgraded to a new version of Unity.

It could be worth looking at some kind of source control to avoid future issues. Github is probably the best but if you only want to have a local backup then TortoiseSVN is quite easy to use. Even just zipping the project every few days is better than nothing.

Thanks,

I’ll start taking it apart now the only third party package I am using is LeanTween for animation. Have removed it and installed again as well.

I made a backup of my files about a month ago and stored it on my google drive, it will still be a lot of lost work but still better than losing a 4 year old project I guess. Thanks for the help

Update: Issue Solved

I managed to pinpoint the issue! It turns out the problem was with the dictionary I use to store nationality surnames. Each nationality has around 500+ entries, and I recently added more entries. After the update, the game started crashing on startup.

I removed the latest entries I added, and everything is working again. It seems the crash was triggered by either exceeding a limit or some unexpected data conflict. I didn’t think this would be the cause at first, but I’m glad it’s sorted now.
