Paramount+ app will not load on 50" Roku TV

This is happening everytime I try and launch the Paramount+ app. It goes to the blue Paramount+ screen for about 1-2 seconds then goes to a black screen for another 1-2 seconds and then goes back to the Roku home screen every time. This only occurs when trying to launch the Paramount+ app. It doesn't happen with any other apps on Roku and has only been happening for the past 2 or 3 weeks. Prior to that it was fine. I am able to launch the Paramount+ app from all my other TVs and devices like iPad, Google Chromecast, Samsung TVs with built in apps. I haven't been able to stream Paramount+ because the app doesn't load.
