I have a scene, which I last moditifed 2 month ago.
This scene includes, among other things, a big prefab called SC_Crashed, which I have not been modifying since 10 Months (both according to windows explorer).

Today I opened the scene and got the error

Prefab instance problem: SC_Crashed (Missing Prefab with guid: f9515aae897255244a74be4412156c70)

I got missing prefab problems before and was able to fix it with the guidance of this article: Solving the Missing Prefab issue in Unity3d | by Ágoston Romhányi | CodeX | Medium

However, this time the guids in the scene and the SC_Crashed.meta are the same. Both are: f9515aae897255244a74be4412156c70.

When I look at the prefab in inspector it looks like this:

Turns out google can’t find any hit on that error message.

When I look at the SC_Crashed.prefab file, it looks pretty normal to me. So the data still seems to be there but unity can’t process this.

How can I fix this?

Thanks a lot.

After a lot of trial and error I figured out, that deleting the meta file and letting unity create a new one, solves the problem.

Thank you. I encountered the same issue and fixed it by deleting the .meta file and let Unity regenerate it.
It was strange that the deleted one and the new generated one showed no differences in VCS.
