Wappler 5 beta to non-beta automatic upgrade fails on Mac

Wappler Version : 5.0 beta 10
Operating System : MacOS

Wappler 4.9.1 was running at the time of incident. Manual re-install of Wappler v5 is required, as the 2nd attempt (with Wappler 4.9.1 closed) simply made Wappler 5 beta (old) vanish from the installed apps
