Excel Find / Command-F crashing on Mac Tahoe (Office 2019 / Excel 16.78) – anyone else?

Excel Find / Command-F crashing on Mac Tahoe (Office 2019 / Excel 16.78) – anyone else?

Mac mini + Tahoe 26.5.

Excel 16.78 (Office Home & Student 2019).

Problem started after recent Tahoe update.

Classic Find is behaving badly and often crashes Excel.

Workflow:

  • click/select a column
  • Edit → Find → Find… or Command-F
  • search for text or email fragments (ex: "kristin" or part of an email)
  • Excel may crash or Find becomes unusable

Things already tried:

  • full Excel reinstall
  • blank workbook test
  • new macOS test user
  • Office container reset / plist tests
  • preference resets
  • same Tahoe version confirmed

Upper-right Microsoft Search appears, but that is not equivalent to classic worksheet Find for email-column workflow.

Question:

Is this a known Tahoe / Excel 16.78 Find bug or Search-routing issue? Has anyone fixed this or seen it resolved with a newer Excel build or update?

    I had the same sort of problem on my laptop. Excel 16.78 crashed each time I tried an advanced find/replace. However, I have Excel 16.54 on my desktop. I simply deleted 16.78 and its icon from the dock. Copied 16.54 across, moved it into the Applications folder. Restarted laptop. Works ok so far for me.

    Thanks for your post. I'm relieved it's a common problem, and not just me!

    I have the same issue on a Macbook air M5. Crashes Excel every time. Seems to have started after the upgrade.

      Anyone think that this will be fixing a future Mac upgrade or fault or we have to now all cave in and be forced to buy their paid version, and what happened to this forum it takes a half a dozen clicks and verifications just to reply and then the email notification doesn't even have the lin to the thread
