Am able to play other providers (YoutubeTV, YOutube, Tubi, etc.), and Roku does allow me to select a program, but it won't play on my TV. It does play on my computer, which uses the same internet service (wired).
You could try removing the ROKU channel from you ROKU streaming player. Then restart your ROKU. Then add the Roku channel back. Your ROKU channel app on your steaming player may have gotten corrupted. Removing, restating and then adding it back might solve the problem
