              OperationCanceledException: Failed to prepare target build directory. Is a built game instance running?
This error keeps popping up more and more often when making a standalone build on Windows. There is no other game instance running according to task manager. Any idea?

              Have you tried uninstalling the target directory, and rebuild your game? I've seen this problem once, and it could be fixed with deleting the files in the target directory, or choosing another directory to build.
