Re: Quickbooks Mac 2019 Layout Designer App Crash

I am having the same problem as well. Also using QB Mac 2019. I also just updated OS to 10.14.3 and the problem still persists. Layout Designer crashes immediately upon launch. This is part of the problem report:
Exception Type: EXC_CRASH (Code Signature Invalid)
Exception Codes: [removed]000000, [removed]000000

kernel messages:
