I've been using a USB-C docking station with my Predator Helios 300 (2021) for over a year now. I had two external monitors connected to it and it was running without issues. However, after a Windows 11 update earlier this month (KB5044380), the Thunderbolt connection no longer seems to send out display information. I can still connect external keyboards, mice, microphone, speakers, and video cameras via the docking station, but the monitors aren't even detected. I have tried with another docking station and get the same result.

I can still connect to multiple external monitors using the HDMI and mini-DP outputs, but it is less convenient than routing everything through the docking station. I have tried updating the drivers for my USB controllers and connectors as well as my GPU drivers, but no luck. Has anyone else experienced anything similar? Any guidance or suggestions would be greatly appreciated.
