Hmm, same for me perhaps. New MBP 16 and Catalina connected to a external monitor via USB-C (a HP Z27 4K UHD). If I leave it to sleep for a long duration, then it panics when waking from sleep and just black screens for a good few minutes, then turns on the fans full blast for like 2 seconds and reboots. I've taken to just shutting down completely when finishing work and not letting sleep. |

In my case, if I use the usb-c port of the monitor to connect the ethernet adaptor, it works for a few minutes and then drops all the packets. This was never an issue before Catalina or with a windows machine.
Another weird issue that I have with this monitor and Mac OS (not only Catalina) is related to the Microsoft sculpt ergonomic keyboard receiver, when plugged to one of the USB ports of the monitor. If I unplug a the MBP and connect a windows machine to the monitor, when I connect the MBP again, there is a >50% chance the receiver will not be recognised. Plugging and unplugging does not work. I have to do a restart of the MBP.
The above make it very annoying when I have to switch laptops. Sometimes I have to work on 3 machines at the same time, which by coincidence run 3 different operating systems (Win 10, ubuntu and mac). The reason I got this monitor is mostly for the build in hub. If it worked properly, I would just plug everything on the monitor and I would only need to plug the usb-C to the laptop and be ready to go. Sometimes it does work and I feel like I am in the future, using a dock that can support every device, with just one universal cable. Now I often have to plug and plug things directly at the laptops.
One last thing for people who might consider a similar set up. Due to USB limitations, if you plug any storage device on the monitor and the monitor is at 4k@60Hz, you are limited to USB2 speeds.
