iPhone stops Recording on its own

I have an iPhone 13Pro. It suddenly stops filming on its own. Sometimes it can record a video for a few minutes before it stops, other times only a few seconds. Sometimes the videos don’t show up in my photo library or they show up as a white image. I have plenty of space on my iCloud (2TB and only a few GB used) I have tried to lower the quality and restart the phone with no success. The phone also gets really warm when I try.
