Ctrl-Home causes Excel to crash

I have a rather large (15 yrs of data, 29 worksheets) Excel file (in Office 360) that crashes every time I hit Ctrl-Home, as well as crashing when I try to scroll left or right using the  scroll buttons in the lower right corner.

Other files work fine using these same actions.

 

Since other files work OK, I'm guessing there's something corrupt in this file, and Excel itself is OK.

Is there something I can do to fix this file - some sort of 'repair' function?

 

Recreating this file from scratch would take weeks.

I might try copying each worksheet into a new workbook, but that might copy the corruption as well.
