Apple display driver causes Macbook Pro 16 (2019) to crash

I wanted to be able to plug my Macbook Pro directly into a 4K display and have charging, data and video data sent over a single cable.

I first purchased a Dell U2720Q display. However, the 2019 MBP Pro 16” kept crashing every time I left the device to sleep connected to the display using USB-C.

I figured there was something wrong with the Apple display driver for that display, so I returned it and then purchased a Samsung C34J791 34” display with Thunderbolt 3.

I assumed that a display with a Mac-specific connector would certainly work. No such luck. The Mac keeps crashing.

Worth noting is that my MacBook Pro 15 (2018) does NOT crash.

Dell is correct in stating that this is not a Dell issue, as the driver originates in Mac OS. I haven't submitted nor searched for a solution for the Samsung display as I'm making the assumption that they, too, have no control over this issue and it needs to be addressed by Apple.

Sleep issue/crashing on the 16"MBP is known issue— and a software update has yet to follow.

The work around is turn off Power Nap in

>System Preferences>Energy Saver (both battery and power source)
