cannot load underlying module for 'Darwin'

Question

I had to move my "Developer" account from some external drive to the internal drive of my Mac.For this I zipped the users folder, copied to the internal "users" drive and unzipped it there.Then I changed the users folder in the users settings. I also updated the permissions on the user "Developer" folder,allowing admins "R&amp;W", the user "R&amp;W" (+ setting it as owner) and everyone else no permissions.I was able to login to the new home dir. I opened my old Xcode project (that was updated automatically in some fashion).But when I compile it I get the error "cannot load underlying module for &#x27;Darwin&#x27;"&#x3D;&gt; What went wrong ?Btw:I already removed Xcode, downloaded it again and placed it into the programs folder - same issue ... :-)
