P: Crashing when attempting to access Map or Web modules (macOS 10.14.6)

If you create a new user account (I did one with Admin), launch LR 8.4, does it still crash?
It doesn't on this end. 

Booting in safe mode doesn't help. So the fact I can click on Maps and Web as a different user, indicates there's something in our main user library that's causing this crash. 

LR8.3.1 Maps and Web works for me.  Please let me know when I should move to 8.4.

Please see https://lightroomkillertips.com/rolling-back-previous-version-lightroom-classic/

How do I revert to LR8.3.1please?  What date was the software update implemented?

Here's my hardware.  Let me know if I can try or do anything else to help.

Found the submitted crash reports (9 in total), it it crashed in one of the 3rd party library that Lr uses to host the google maps. The dev team would need to investigate. So far you're the only customer who reported such type of crash.

Please revert to Lr 8.3.1 to continue your work.

Ok. I see a bug logged for the crash signature that Andy and Paul are seeing. Not seeing yours. Might be under a different email address than you use to log in here...

Thanks. I see your crash log.

Hi Paul. I already found your crash log. These are the instructions for submitting a log: https://helpx.adobe.com/photoshop/kb/submit-crash-reports.html

Jeff, I am signed in when the crash occurs. I have tried uninstalling then re-installing Lightroom, turning off GPU Acceleration, removing Lightroom's preferences and opening another catalog. The crash is instantaneous, no beachball. 

What email address should I use to submit the crash log to Adobe?
