Hi there, I uninstalled Safari Technology Preview with AppCleaner and everything was moved to the trash. When voiding the trash, a folder named "com.apple 19-04-46-245.SafariTechnologyPreview" seems to be locked ("in use") and it is impossible to delete it. I installed STP again and uninstalled it only to get to the same point, this time with "com.apple 12-34-22-971.SafariTechnologyPreview" adding to the first folder in the trash. They both contain a "Safary Family" file which opens like a folder but doesn't have an icon nor an extension. Thank you for any suggestion!
