Why is Outlook on my Mac suddenly crashing consistently?

I have been trying to open Outlook on my MacBook Pro all day, and it has consistently crashed. I was just using Outlook last night and had not made any changes to apps or settings since trying to open Outlook this morning. MacBook is running Sonoma 14.3.1. Never any issues until now. Consistent error messages....even after uninstalling and re-installing...per Microsoft support which was not very helpful.

Below is the most recent message I received (minus hundreds of lines due to character limits).

    I have the same problem with my Mac Studio and macOS 14.4.1.

    I've tried reinstalling but still the same behaviour: Outlook crashes after opening

    And it doesn't matter if connected with WiFi, Ethernet or offline. Still crashing. I've tested these versions:

    • Application Version: 16.83.0.24031120
    • Application Version: 16.83.2.24032318
    • Application Version: 16.83.3.24033013

    All the Crash Reports have the same line in the first part

    uncaught ObjC exception, reason: The window has been marked as needing another Update Constraints in Window pass, but it has already had more Update Constraints in Window passes than there are views in the window.

    Had this problem for a couple of weeks and suddenly it started working again. Sadly, no idea why. Sharing this news in case it brings some hope that this too shall pass (maybe).

    I'm afraid my excitement was premature... after a few hours, the problem came back. So disappointed.

    But you are right! Now my Outlook works just normally... I guess it will not stay like that 🥴

    Same problem here. I reinstalled 3 or 4 times and it still doesn't work.

    And when I switch to Legacy, I lose all the emails that are on the computer and only get whatever is on the server (I use POP for a variety of reasons).

    Very frustrating!
