When I build my game it gives me this error 'Assets/Builds/Build_0.01_Data/Managed/Assembly-CSharp.dll' shouldn't be queried by IsAssemblyCompatible, missing IsInternalOrCompiledAssembly check ?

I have made a 2D game using C#, the game works fine in the editor and once built, but after building the game upon returning to the editor I am faced with the error "Assets/Builds/Build_0.01_Data/Managed/Assembly-CSharp.dll' shouldn't be queried by IsAssemblyCompatible, missing IsInternalOrCompiledAssembly check ?" I've found deleting the newly created build files gets rid of the error but it returns once the game is built again. Thanks in advance!
