Would it help if grub saved your last boot option? In other words, if 
you do boot into Windows, the next time you reboot, the default choice 
will be windows? If so, the attached patch might help (if the list 
allows text format patches). It's from a 22.04 system (I don't have 
23.04 installed), but /etc/default/grub has not seen a lot of changes 
over time. I hope it helps.
