Compilation failed because compiler couldn't be executed....

What I did was exporting my project for google build but just after the build finished building, Unity started to showing various DLL files error in Assets/Bin folder. Now I can’t play it as It is showing various errors for which I couldn’t find a solution on Google.
So I tried some steps by my own…

  1. Trying to run the same project in my friend’s Laptop…Same error
  2. Deleting every folder from project except Assets and Project settings…didn’t work…
  3. Created a new project and copied Assets and Project settings from the faulty project to the new one as New project or other projects don’t have those errors…even this didn’t work.

I don’t want to lose my project so If there is any help You guys can provide…Please Help…

Try delete Library folder. It work for me.

I think you built the project in wrong place.

From what I can see, Data/Managed folder does not belong in your working project.
