I'm sorry you're having this experience. If it's a brand new tv, why won't Walmart take it back? Do you not have the original packaging or something? (There must be more to that situation. I thought they give you 30 days.).
If you can't return it, I would contact Onn to start the warranty process. If Onn tells you to talk to Roku, tell Onn that your warranty is with them. Roku's essentially denying there's any problems (if you look at this forum). Let Onn know that you'll file a formal complaint with the FTC and your state AG if they're trying to evade their warranty to you.
For self-help, you might try home>settings>system>power>restart. (If "fast start" is enabled, I would disable that. It can cause problems.). Usually when streaming apps don't work, Roku tells you to remove the app, do that power-menu restart, then install the app. (If that doesn't work, they tell you to talk to the streaming app's support. But, it's hard to believe all these apps are having trouble.).
You could try factory-restart, but tell it you don't have internet ("i'll do it later," but don't do it). That seems to use a less buggy version of Roku's software. Then use something like a $22 Firestick Lite to stream through an HDMI port. You shouldn't have to do this. Onn should fix it (if you can't return it). But, if you ended up without any options, that might work. Others are doing it. If Onn fixes the tv, you might still consider doing that because Roku's updates don't appear to be tested, and break tvs. It could be wise to disconnect from that anyway.
