Disconnect Minutes After Entering Temple

Hi,

I'm playing poe2 on PS5, US west.

Since about 2 days ago, whenever I enter my temple (with my main character in Fate of the Vaal) , after about 5-15 minutes clearing rooms, I'll get disconnected and sent back to main menu. The game says 'unexpected ...', then I enter the game again, temple cannot be re-entered.

Currently my temple is getting destructed because of this.

At the same time, my alt can play temple just fine.

Could you please help? Thanks.
