Game crashing in maps often since switching to CoC spark BM

So I've been enjoying this league quite a bit and with the economy being good for noobs that don't mind a bit of mindless farming, I actually managed to build myself a half decent blood mage.

After 300ish hours spent this season, and few different builds and characters, I haven't had any real issues with game stability up until I upgraded my CoC spark BM. Since then I have been barely able to map without crashing my game. Working on my temple, I've been doing t15 6 mod maps, with a single irradiated or boss tablet so I get level 80 mobs. I run through the map quickly, just sniping the vaal crystals and going straight to the boss. Usually around 90-120 seconds per run.

For the past few days however, I will start crashing mid-map. First sound just stops entirely, and a few seconds after the whole game will crash and close. I'm on console (PS5), so I always send the crash report along with a video report for it. I then have to reload the game, log back in and I'm right where the game crashed. So I don't lose the map or run. But it has started to happen so often that it sometimes takes me multiple reloads to finish a single map. And what's more frustrating that it just randomly happens, haven't been able to pin it down to any specific map mod or terrain. I was hoping that, if someone else has had any similar issues that I could get some help. I have been jumping around different European servers to see if thats the issue, but connectivity has been fine.

I'd really appreciate any help, it's getting to a point I'm not really playing anymore, because I can't really enjoy zooming while just waiting for the game to crash again.
