Latest QGIS 3.2 compilation crashes on opening - Macos High Sierra

Had to trash the QGIS3 folder from ../user/Library/application support
This way QGIS starts but we loose all the definitions and installed plugins.

Similar problem. After attempting to use GRASS tools to edit / digitise existing GRASS vector map. Trashed QGIS3 folder as above and GIS re-started.

Also experiencing this issue, won't get beyond opening 'QGIS 3.2 Bonn' boot message.

Please test on 3.4

On High Sierra (10.13.6).

Recent QGIS 3.4.2 started crashing on startup after months of stability. Attempting to work around:

• removed the profile directory from ~/Library/Application\ Support/QGIS/QGIS3/profiles (no help).
• installed the latest python.org python3 3.6.8 version.
• installed QGIS (3.4.3-1) from QGIS website.

The crashes still happen on launch of QGIS3.app

Any hints about workarounds would be greatly appreciated!

Further to my report above, here is a relevant snippet of the crash report:

A further note on my crash involving a workaround: I installed qgis3 using Homebrew and found that it indeed avoids the crash. There are other issues with PyQt5.sip not being found -- apparently preventing Python integration from working -- but QGIS 3.4.3 does indeed run. I will look into the .sip issue more deeply later, but for now I have work to do with QGIS...
