Loss of items

Hello, I logged out yesterday around 5 p.m. in my den. When I reconnected at 1:17 a.m. I was in the clearing without a spell in my action bar with half of my stuff in inventory and my head and my boots were missing which I couldn't find. Do I have an explanation? And what can I do?
Ps: I play POE 2 on ps5

I bought back my head and my boots that I was missing for 8 divin to be able to play. I realize when going into my atlas to do mapping that I am missing half of the atlas map, the whole beginning, therefore the end-of-game boss summons.

Ps: After reconnecting to the games my atlas came back (but not my stuff)
