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?
