    Since using Unity 2018.2 and later versions with my project i often get the error:
    "Copying assembly from 'Temp/Assembly-CSharp.dll' to 'Library/ScriptAssemblies/Assembly-CSharp.dll' failed".

    I only get this error after changing something in a Script and switching back to Unity.
    I can fix this only by restarting Unity or by going back and change the script so it's missing a ";" at the and of a line, then switch to unity so an script error shows, and then putting the ";" back, because then everything works fine.

    Is there a way to resolve the problem?
    Struggling with always needing to quick fix it, instead of overall fixing it is not so nice.

    I also have the same problem here! I must restart unity several times a day because of this.
