Bug [Solved] Unity claims scripts are missing that are there. it can even show them in the root prefab

Hello,

yesterday my game was working 100%. No issues.
Today I open Unity and my game is broken!

Unity claims 2 missing scripts on many prefabs. Yesterday they were there.
The root prefab shows the script's name but the script component has the name "Script" instead of the scripts name, see attached file "root prefab".

When I click on the scripts name, the project view jumps to the script. It is there and Unity knows it???

In prefab variants the scripts are claimed to be missing, although they are clearly not! , see attached file "prefab variant".

There are no compile errors.
Reinstalling the package those scripts are from doesn't change anything. That makes sense to me because the package was not updated. I know this since it is my own git package.
Restarting Unity also doesnt help.

I did get a blue screen while opening my Unity project this morning. After restarting the PC Unity opened as usual but now claims these missing scripts that are clearly there.

Please help me.

 

What does your version control history tell you?

 

nothing that makes sense to me. The only thing that seems to have changes is "PackageManagerSetting.asset".

I already reset to yesterday's last commit. nothing changes. That makes perfect sense, since nothing has changed.
If anything changed on the Unity file structure it is outside of my version control. So maybe in the git exclusion file

I did however get a blue screen when opening my project this morning. After a reboot it opened, but now claims these missing files.

When trying to add the same scripts to a new prefab I get an error stating "Can't add script component 'ProjectileWeapon' because the script class cannot be found. Make sure there are no compile errors and the file name and class name match."
Both is the case. There are no compile errors and file & class name are the same

 

Try deleting the Library folder with the project closed. Possibly some stale or corrupt cache data, especially after a bluescreen.

If you happen to see bluescreens more than once per week (or even per month depending on how intensive you use the PC), you should definitely update drivers and perform a hardware check, preferably with some intense check tool that boots off of a stick or floppy.

 

oh dude THANK YOU!
Deleting the library folder fixed it. The blue screen was surprising to me, it's not normal for me to get one. Not sure what happened there. But the main thing is that my Unity project is not screwed up.

Thanks again!!!
