"Mode Not Supported" -- suddenly won't play Netflix

I have a Roku Premiere+ (Model 4630X) and for the last couple years I've played it on my Samsung 4K TV with no problems. A few days ago, I stated getting the below error screen whenever I tried to play something on Netflix. If I unplugged the Roku and plugged it back in, though, it would work. Today even that isn't fixing it and I can't get it to play Netflix at all. It will stream YouTube TV just fine, though, which is also through Roku and is using the same HDMI cable and port.

I went into Roku settings and had it auto-detect my resolution, which it correctly set to $K HDR at 30Hz HDCP 2.2.

I have the exact same issue with the same equipment. Tried switching HDMI cable but the problem persists. The only thing that works is unplugging and replugging. And the issue is only wit Netflix.

Exact same problem and solution, it works everytime I unplug and plug it in.

One you've performed the update, try changing your display type selection back to Auto in Settings>Display type.
