The Kernel Panic is referencing a GPU issue. Unless the external display is causing the problem, the Logic Board on your laptop has probably failed and will need to be replaced. Disconnect all external devices in case they are causing the problem, but if you continue getting the Kernel Panics, then it confirms a hardware issue is most likely. Normally I would consider the possibility of third party software causing the problem, but that is unlikely here. The Logic Boards on the 2019 models (especially the 16" models) have a higher rate of failure than other models both based on personal experiencing supporting my organization's Macs and from reading this forum.

Try running the Apple Diagnostics to see if any hardware issues are detected. Unfortunately the diagnostics rarely detect any problems. Unfortunately if the Apple Diagnostics or Apple's service diagnostics don't report an issue, then you may have trouble getting Apple to repair the laptop. If you can show that a clean install of macOS also gets Kernel Panics, then that will enough proof to convince Apple of a hardware failure. A clean install of macOS is when you erase the disk followed by reinstalling macOS (for an Intel Mac, you can erase the whole physical SSD). Do not install any third party apps and do not restore from a backup, otherwise you may be bringing back possible software issues and Apple won't trust the results.

I appreciate your response. After attempting Apple Diagnostics and finding no issues, I experimented by removing the battery from my MacBook Pro 2019 16-inch. The result was significant lag, as the logic board didn't receive sufficient power, forcing the system into safe mode with noticeable performance issues. Upon replacing the battery with a high-quality OEM battery, my MacBook now runs smoothly.

While some articles suggest logic board failure as a potential cause, I believe, in my case, the root of the problem lies with the battery. Changing the battery resolved the issue, and my MacBook Pro is now performing well.

Interestingly, I've observed that many MacBook Pro 2019 16-inch devices are sold at a low price in my country due to this problem. However, it appears that the actual culprit is often the battery, leading to a misconception about a widespread logic board failure.

Having successfully addressed this concern by replacing the battery, I now have five MacBook Pro 2019 16-inch devices for my employees, all running smoothly.

Very interesting. Please update us after several weeks or so to see if it still works without any Kernel Panics.
