Scripts suddenly stopped working!

Hey,

while i was on my project, all the scripts attached to any gameobject worked properly until, without any change made, all showed this error: "The associated script cannot be loaded, please fix any compile errors and assign a valid script"

while i tried to reattach them ive got the error: "Can't add script component 'Skeleton' because the script class cannot be found. Make sure that there are no compile errors and that the file name and class name match." (the script name and the class name are identical)


what should i do?

 

Can you add a new script?

 

once was happened to me te same, the problem was the heritage.
The scripts were unconfigured and did not inherit from monobehaviour, check it.

 

no i can't.

thats exactly the error but all the scripts that i have starting like this :

Code (CSharp):

1. public class Player : MonoBehaviour
2. {
3. ...
4. }

 

I have the exact same Problem after Updating to 2019.3
