Nearly identical specs as above poster. Same issues hard locks after 10-20 minutes. Resetting by toggling PSU power switch is only way to reboot. Using Cura 4.4.1 and also tried 4.2.1 with identical issues. Willing to go farther back if anyone has tried successfully....? Desktop Specs: Windows 10 pro AMD 2700x GTX1080 16GB RAM @3400mhz M.2 1tb SSD, 500gb SSD, 3tb SSHD, 4tb StoreMi Tier Drive. Cura works flawlessly on my Intel 7700HQ/GTX1070 laptop.
