Scene and a prefab not working (probably corrupted) after hard reboot

Hello,
I was looking on chrome for an answer for a problem in my code when my computer became strangely slow, I opened task manager and it slowed down even further. Most apps were frozen, the keyboard didn't work. Couldn't even shut down the computer from CTRL + ALT + DEL. All I was left with was to hard reboot the computer.
This is strange as it has never happened before, maybe a memory leak?

Anyways, when I opened Unity, my scene couldn't load saying, Unknown error while loading scene "Level 1".
Also, my most important prefab is broken. I looked at it in a Hex editor and it looked mostly fine. I messed around with it and I got it to have a different, working prefab on it with its game objects but having the previous components. The components and their values were the same so the data is there somewhere.

I have looked on multiple other threads and I have tried re-importing and duplicating the prefab but with no luck. I attached an image of how the prefab looks like if its any help.

Does anyone know what I could do to solve this?

 

Revert to the most recent working commit via version control.

If you are not using version control, slap yourself in the forehead and realize what a foolish mistake you've been making, and start using it.

 

You might also try reimporting the scene or prefab (right-click- reimport)

I'm sorry you've had this issue. Please consider using proper industrial-grade enterprise-qualified source control in order to guard and protect your hard-earned work.

Personally I use git (completely outside of Unity) because it is free and there are tons of tutorials out there to help you set it up as well as free places to host your repo (BitBucket, Github, Gitlab, etc.).

You can also push git repositories to other drives: thumb drives, USB drives, network drives, etc., effectively putting a complete copy of the repository there.

As far as configuring Unity to play nice with git, keep this in mind:

It is only simple economics that you must expend as much effort into backing it up as you feel the work is worth in the first place.
