Thanks for providing the information. I don't have nearly the experience with Roku TV devices as others, so I feel you would be better served by someone much more experienced with your platform. Yeah, Roku is Roku, but the TVs really are a little different. Not a lot, but enough that I don't want to cause the problem to get worse.
I can help gather information for the Roku TV experts in the meantime. So...
Are you in the US? Are you using a VPN?
Assuming US and no VPN, what happens when you launch other apps. Describe launching, say, Amazon Prime Video. (If you don't have Prime Video, pick another and let us know what app it is in your response.) What version of the Prime Video app is on your device? Options button (asterisk) will bring that data up, to include the version and build. Did you try the Update option from that menu?
When you launch it, what happens? Splash screen? Do you get the menu inside with content showing? Does it crash immediately? Does it attempt to launch the content then crash? Describe what's going on, in a timeline format (along the line of "launched the app, splash screen for 4 seconds, menu displayed, selected Generic Movie, began playing for 3 seconds, screen went black, Roku rebooted" or whatever).
This will be helpful for the Roku TV Experts, who may be able to get you running like you should.
