Lag when browsing between tabs since patch (PS5)

Since the patch <24h ago, there's a lag spike everytime when opening the Stash and moving to another tab.

It always happens from 1st to 2nd tab, might be because the 2nd tab is Maps and filled with 400+ maps, but I had more in previous leagues and it didnt cause any problem.

I'm playing on PS5, wired connection, no other issue experienced (except the infamous sound crash, along with another lag/latency when entering the underground Betrayal encounter. Also happens every single time. Both the Tab and Betrayal lag cause the game to freeze for 2-5 seconds.)

Edit: It's not related to my internet connection because it doesnt happen elsewhere, only sometimes when switching between tab 1 and 2 and everytime when entering Betrayal Research
