Laptop Freezes when Joining Zoom Video Meetings

Hi, two of our users (both using Precision 5680s) their laptops will completely freeze when joining a Zoom meeting. It doesn’t happen initially after a laptop reboots but after 15 minutes or so of work, the freezing will begin when joining a video meeting. We’ve tried updating all drivers (including Intel GPU, camera and BIOS) and clean reinstalling Zoom. Do you know what we can troubleshoot next or what might be causing this issue? 

They’re using an i9-13900H 5400 CPU and it just seems strange issue happened a couple weeks ago but has only happened to those two users.
