b.  If there is a machine where you can open the file (older build of Office 2016 or older Office versions):

1. Open the file
2. Go to VBA IDE (by pressing alt + F11)
3. Go through each forms in design mode and see if any of them has ‘Cycle’ property as ‘2’(fmCycleCurrentForm).
4. If any form/frame has such value, make it ‘0’ (fmCycleAllForms).

Note: Issue can also occur if any ‘Frame’ control is set with cycle property ‘2’ as well
