Trouble Accessing U-verse TV Account on My TV

I've been having a bit of trouble with my U-verse TV account recently. When I try to access it on my TV, I'm encountering some issues. The screen just stays blank and doesn't load anything.

Has anyone else experienced this problem? Any suggestions on how to fix it? I've tried a few troubleshooting steps but haven't had any luck so far. Would really appreciate your help!
