BF6 Overheats PS5

Past couple of days I’ve been having issues with BF6 shutting my PS5 down. I got my PS5 back from the shop today after getting the Liquid Metal replaced and professionally cleaned, but after 4 hours it shut down again, & I don’t want to keep playing if it’s going to damage my console. Has anyone found any fixes for this? Is it something other than the heatsink or Liquid Metal? Or maybe just optimization issues on EAs end?
