recent app updates on Mac

I updated MS Outlook on Mac via App Store. Unable to move an email to calendar (i.e., dr. appointment notification).  Outlook closes, error report is 'sent' and the is what I get:  (only a partial view as the error message is literarily over 10 pages long). 

Microsoft Error Reporting log version: 2.0

Error Signature:

Exception: EXC_BAD_INSTRUCTION

ExceptionEnumString: 2

    Yeah, I’d be a little cautious with major app updates on a work Mac too. I usually wait a few days and check whether others are reporting any bugs before updating. If the update is already installed, clearing the app cache or restarting the Mac can sometimes fix odd behavior, but I’d avoid rolling anything back unless there’s a real compatibility issue.

  • After the update, issues appeared. My suggestion is to reinstall (to fix possible errors during the update). If that doesn't work, I suggest reinstalling completely (remove and install).

      I performed the installation more than once, and the problem repeats in an infinite loop.
