Since the problem is associated with the F4 key, it is vital to check if function keys are locked. Many keyboards have an Fn Lock feature. When you enable this, it forces function keys to act as multimedia buttons, and the F4 shortcut no longer works.
In such a situation, consider disabling the lock by pressing the Fn + Esc or Fn + F4, depending on your keyboard model.

If add-ins are conflicting with the Excel app and triggering the F4 key not to work properly, disable them one by one and check if the problem is solved.
Here are the instructions to turn off the add-ins in Excel:
- Open Excel, go to the File >> Options >> Add-ins.
- In the opened window, choose the COM Add-ins from a drop-down menu >> hit Go.

- Now, unselect all the checkboxes >> click on OK.
- Reboot your Excel file.
