Hi,
Did this issue only occur with the special file? If yes, I agree with Bernie, please try his suggestion first. And we also can copy/paste all the content of file to a new Excel file to test.
If this issue still exists, please open Event Viewer to check whether there's any error about the Excel crash issue.
Press Win + R, type "eventvwr" in the blank box, press Enter. In the Event Viewer, browse to Windows Logs -> Application, there may be some errors after the crash.
To protect your privacy, you may send the error logs to
ibsofc@microsoft.com, we will try to find the cause.
Regards,
George Zhao
