PS5 performance troubles

I've been trying to play your game on a PS5 console for about a month. The console is connected to the internet via an ethernet cable, with 800 Mbps bandwidth, and the ping to major internet services is around 20-40 ms.

I've been constantly experiencing technical difficulties while playing. There are interruptions, freezes (this is the first time in 4.5 years of using a PS5 that I've seen a game freeze on a console), and sudden, endless loadings from one location to another (forcing me to restart the game). Something as simple as opening and closing the inventory can cause the game screen with the character and environment to not render, everything is foggy, and only NPC signatures are visible (if in a city). The only way to fix this is to restart the game.

For the last couple of days, I've been playing through Atlas, searching for Corruption to complete the quest where you need to complete the 15+ Corruption. I found it, launched the map. I was kicked out of the game halfway through the map. After logging back, I'm back in the Vault. There's no portal to the map (the map had 0 resurrections). The Corruption is also no longer visible on the Atlas map. There's no more corruption anywhere in the open areas of the Atlas map; I need to start searching from scratch.

Can you tell me what the possible solutions are? Should I play on a PC with a terabyte of RAM and a cluster of graphics cards? Should I rent a room in a building next to your data center?

Is there any way to credit Ирсиус in the Fate of Vaal league for this damned quest and give him the book with the Atlas passives?
