Should i make a new project or start a new scene

I’m currently making the biggest project I have ever attempted to work on and have run into an error “iterator == end” I found out this is usually corrupted data I found it and removed it. although the scene relied on it and now is permanently inaccessible, even with reimporting every asset I can no longer access it. I can easily remake the scene but should I just start a new scene or make a clean new project to avoid any possible further corruption.

Just roll back to your last known good copy of the scene in version control.

You are using version control aren’t you?
