If won't help, check your log files for details by going to Help menu and Open Log Directory.

For example by dragging & dropping the log folder into newly opened Terminal window, and run:

tail -f *.log

then run the build again and check the reported logs. Hit Control-C on Terminal when finished.

For better visibility, run:

tail -f *.log | grep -C5 -i error

You can also try to clear cache folder of VisualStudio, e.g.:

$ lsof -p $(pgrep VisualStudio)
$ rm -fr ~/Library/Caches/com.microsoft.visual-studio
