Apps suddenly offload

[Mirlohi]

Recently i have experienced that I’m using an app, I quit it for seconds or minutes and when I come back I see the app offloaded and I have to download it again.
My IOS version: 16.1.2
Apps that experienced this problem:
Whatsapp
Google map
YouTube
Space left in my phone: 500 MB

Welcome to iPhone Forums!

WhatsApp alone needs more than 4 GB of storage on my iPhone.

In case you haven’t done this yet: Go to Settings - App Store, scroll down to “Offload Unused Apps”, and make sure it’s disabled.
