Whenever my two Dell U2718Q 4K@60hz monitors are hooked up via DP HDCP stops working. Nearly every streaming app and/or Safari shows a black screen, throws an HDCP error, or downgrades from UHD to HD. I've tried hooking up only one monitor via HDMI and the same thing happens. HDCP only works when no external monitor is hooked up.
HDCP test for Chrome:

I am running macOS 13.1 on a MBP 16" M1 Max. Does anyone have working HDCP on external monitors? Anyone know how to fix this?
