I had to upgrade my Roku stick recently to a Roku Streaming Stick 4k+. Everything works as expected except YouTube. Whether browsing in YouTube or watching videos or even ads, the screen goes to black constantly. hitting any button on the remote brings the screen back up but it goes back to black again shortly after. It's almost like it keeps going into sleep mode. I have updated the Roku software. I have deleted and reinstalled the app many times over. I have experimented with playback setting both in the Roku settings and in the app settings. Nothing works. I think there needs to be a bug fix by either Roku or google.
After removing the channel, did you restart** your Roku to clear its memory cache BEFORE reinstalling the channel? Without the restart you may not get a clean reinstall.
Depending on your Roku model you'll find the "System restart" option under either "Settings > System > Power" or if you don't have the Power option, under "Settings > System". If you don't have sufficient control to use the menus, or if it is just more convenient, you can also restart by pulling the power plug for a short while, then plugging it back in.
**On a Roku TV with "Fast TV Start" enabled, turning the TV off/on only puts you in/out of a low power standby state, it does NOT give you a complete restart. Use the methods above.
