Downgrading from Safari beta

by DeMoGraph   Last Updated July 11, 2018 21:12 PM

Installing Safari beta version is apparently only possible by replacing the builtin Safari version. In this case version 11.1.2 with 12. If beta version does not work, gives too much trouble or is just unpleasant:

How do we downgrade to an official stable version, currently Safari 11.1.2 for 10.12.6 Sierra?

I tried to restore everything relating to 11.1.2 from a backup (going by what is found that is in the installer package), I located and re-applied the 11.1.2_Sierra.pkg. Yet Safari now refuses to work entirely.

Crashed Thread:        3  Dispatch queue: com.apple.SafariCore.RemotePlistController.internalQueue

Exception Type:        EXC_CRASH (SIGABRT)
Exception Codes:       0x0000000000000000, 0x0000000000000000
Exception Note:        EXC_CORPSE_NOTIFY

Application Specific Information:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[_NSPlaceholderData initWithContentsOfURL:options:error:]: nil URL argument'
terminating with uncaught exception of type NSException
abort() called

Is there any way around re-installing the entire system?
