, remove the file
Library/ScriptAssemblies/com.unity.multiplayer-hlapi.Runtime.dll
and now build works again, once only. The file-removal procedure has to be repeated for every build

Me too. For some reason Unity changes my folder to Read Only every time I open a scene, even if I ticked it off before. Any clue guys? Thanks a lot

I solved this issue by checking that the folder was not set to Read Only in windows explorer properties
