Welcome. That’s a nice motherboard. I have run into something elsewhere that might be linked, if only by Software Utility Suite.
ASUS recommends and runs a utility called AI Suite. In April of 2019 a new version came out. It has caused a few problems, specifically with BattlEye. That doesn’t mean it isn’t involved in your Hang. Please go here and read about the new version:

Please also look to see if you are governing your Frame Rate. Your GPU software may be “gating” a Frame Rate that your PC can’t handle, and it’s Fatalling Conan Exiles. This does happen on newer ASUS ROG machines/frameworks/boards.
