I do have an Asus A17 Tuf Gaming, with Ryzen 4600H and nvidia 1660Ti Mobile, this worked fine with Tumbleweed for over a year, even so the USB-C monitor is only recognized on boot.
yesterday I ran zypper dup and 4550 updates where installed over night. I restarted the notebook and the support for the USB-C conenction to the nvidia card is gone. HDMI is still working.
