Welcome to the Roku Community, @GameLord392024
We understand you are having an issue streaming with the Disney Plus channel on your Roku device. Thanks for the steps you have taken to resolve it.
Did you restart your Roku device before re-installing the affected channel? That step is crucial when performing troubleshooting.
If you haven't tried the suggested order (remove > restart > re-install), we would recommend giving it a shot once again.
We also suggest doing the restart from the Settings menu by navigating to Settings > System > Power (If you do not see a Power submenu, skip to the next step.) > System restart.
Please keep us posted, and we'll continue assisting you from there.
All the best,
Chel
