Sometimes my Pulse Elite disconnects mid session, at first I thought it was because the USB adapter was on the back and it can get rather hot but then I moved it to the front with a USB-C to USB adapter and so far it's worked fine but I do get the occasional disconnects here and there. (charging my headset to full seems to minimize this scenario)
Other than that, I'm quite happy with my PS5 Slim.
I think I've only had 1 or 2 system errors while playing Helldivers 2; mostly me messing with the settings mid loading screen.
