@B24R-
Have you tried restarting your Roku?
These things are just special purpose computers. Like their big brothers sometimes clearing things out by restarting them can correct problems.
Depending on your Roku model you'll find the "System restart" under "Settings > System > Power", or if you have no Power option, under "Settings > System".
If a restart doesn't do it, or if you don't have sufficient control with the remote to navigate the Roku menus, you can also restart by pulling the power plug to the Roku for a minute or so then plugging it back in.
