You're on a laptop. Those things overheat easily. Then they have to slow down to protect themselves, and the recording falls apart.
Laptops are generally meant to be easily portable, load something quickly, and then sit and cool off while the user looks at it. Live media production doesn't allow it that time to rest.
Gaming laptops are slightly better than most, but not necessarily all the way there. Media and gaming specs are similar, but the workloads are just enough different to still be a problem.
A desktop tower would be the best solution, but if you must use a laptop, look at the "Mobile Workstation" class of machines. They're not designed for anything in particular, except to keep their (good!) published specs at full throttle indefinitely. Gaming laptops are actually a step down from that, being optimized for a specific purpose.
