Grounded keeps crashing my ps5?

It's only an issue that's concurred recently. I've played 100 hours on my ps4 edition and when I bought my PS5 from my boyfriend we all made a new save for the PS5 edition. We have nearly 30 hours in the save but recently grounded at random intervals completely turns off my ps5. I wont be doing anything drastic, only like running back to base, loading a save, fighting.

it has happened fours times where just boom. My monitor turns off and now my ps5 is completely turned off without warning. No message, no warning just gone and it fully rebuilds the system every time which has worried me to losing all my content on my ps5 if it doesn't build properly. I fully dismantled it and cleaned out everything with an air gun to the same issues.

I've tried other taxing games like Red dead 2 and overwatch on the highest graphics and other small games that are fairly buggy but none have the same result.

Its not my outlet, nor has it occurred with any other games but I really want to figure out a reason because my friends and I are really close to 100% the game and we've all been getting frustrated with this issue since I'm the host 🥲.
