I'm having the same problem on PS5 after the latest update.
This evening I played for around 3 hours and had over 10 crashes of different types. The first is where it just crashes back to the PS5 menu and gives you the option to report but no error code. The second type of error is mid game the whole screen freezes and you have to physically close the game down. This second one must be server related, as I was playing with a friend and we had the crashes at exactly the same time.
Having played the battlefield franchise since bad company I am appalled at how bad this game has become with clearly little to no QC before updates are released. When you are paying £80 for a game you do not expect to be beta testing. I just hope the EA / Dice do something to recognise these issues for fans who have forked out hard earned cash otherwise this will be the last product I buy from them.
