iPhone 16 Pro Max apps not opening and storage issues after update 27.2

I would recommend making sure that 

1. you have twice as many GB of iCloud storage as the size of the phone.
2. Everything, yes everything is sync'd to iCloud in Settings, iCloud
3. Having ensured that the sync is complete, wait maybe 2 days, you then 
4. Backup to iCloud (which will be smaller size now)
5. Erase all content and settings
6. Restore the backup - this will reduce system files to a minimum and reestablish Photos with thumbnails
7. Watch out for Youtube and apps like TikTok and Insta, which can simply be uninstalled, Whatsapp which needs serious data reduction usually

Downgrading isn't supported by Apple.

Have you gone and deleted or offload data off your phone so you can gain back more internal storage?
