Prefab Broke

Hello! I have a serious problem!

When importing asset from asset store, I did not see that asset will replace some files of my project.

Thus, he replaced me with one cs script and my character’s prefab.

What should I do now? How can I restore the replaced script and most importantly the character’s prefab ???

Using recovery programs (R-Studio), I was able to restore the prefab and meta, but when I try to insert it into the project, I get a message



Maybe it was restored incorrectly, or maybe it can’t open because the prefab refers to a script that is now also broken. I'm in panic.
