Excel Crash When Defining Names

Question

Formulas > Define Name to create a worksheet specific named range caused Excel crash without any error message. The issue happened every time for a specific spreadsheet. But for other excels, it seems fine.

Macros that call .Names Add Name:=… fail as well

I used to copy all raw data to a new blank spreadsheet, and re-built all VBA scripts in the new one. The Add Name worked fine for a moment, but some time later, the crash started again and cannot be recovered.

I am using Windows 10 version 1909, Excel for Microsoft 365 MSO (16.0.13801.20840) 64-bit

Any ideas that I can prevent this issue?
Thanks!

Answer 1

I figured out that the 64-bit excel messes the names up, whereas the 32-bit is fine.

To me it is an excel bug, try with the 32-bit version.
