Apparently Common Roku Home Page Issue
I have the Roku Express 4K Plus.. periodically on the homepage all choices will disappear except for Home Streaming Channels Settings It's a pain in the rear, in the past I was able to unplug it ...

I don't know what causes this, but you might be able to recover faster via Settings > System > Power > System restart, or systems without the Power option Settings > System > System restart instead of fumbling around with power cords.
