Usually these services automatically starts after the server restart, if not you can manually restart as you have tried.
Try Restarting the windows server again. if problem continues...
I think with the server upgrade file system has been changed that's why you get this error.
This is a configuration issue ,Path need to be changed in registry editor.
Please find the path of services.exe in tableau server folder, it should be same as path of respective service in registry editor.
Request windows team to deal with it,wrong update in registry editor will affect whole machine.
Hope it helps.
Thanks for response .
