I would start a warranty claim with the manufacturer. They'll probably tell you it's Roku's problem (Roku will string you a long forever. This thread started a year ago. Lots of "passing it along.").
Roku doesn't test its updates, and you may have been updated with a particularly bad once since November (I got my reality check Dec. 20.). You can look at home>settings>system>system-update. It will tell you when your tv was last updated.
If that date coincides with when your problem started (or, even if it doesn't), I would try home>settings>system>advanced factory-reset. During the initial setup, tell it you'll setup the network connection later (but, don't ever do it). This seems to load an older, less buggy (less updated) version of the software. You could stream through HDMI with an inexpensive external streaming device. (I'm using Firestick Lite. $22).
That's not a bad way to just move on, without having to buy a new tv, or deal with people who don't want to warrant their mess. Even if you got the tv manufacturer to fix it, Roku's untested updates are like a box of chocolates. You'll still be vulnerable to being broken. (Lots of people here with green screens, and the famous Roku never-ending recovery loop. The years' long mac-addr zeroes problem. After you realize how little regard Roku has for its customers, there's a lot to be said for cutting the cord from Roku, and keep your options more modular -- not all your eggs in one basket.).

"People are often amazed at how much we’ve done with the number of engineers we’ve got." (Roku CEO Anthony Wood, Austin Statesman, Oct 4, 2019). "Amazed" is one way of putting it.
