Obviously this issue has been going on for 8 months! I would call it a design fail for the Express units since they have no vents to let the heat escape. This is the part that makes me laugh (from https://support.roku.com/article/226794787😞 "If the problem persists, then you should stop using your Roku player."
Bingo! It’s called “planned obsolescence” and roku will let thousands of us , if not hundreds of thousands of us go round and round here instead of being honest and telling us we have a pet Brick named Roku. A Sick way to do business. Time to replace ha ha they win.
I've been having this problem for months, sometimes just unplugging and plugging the Roku power cable back in resets it and it works for a bit, but ultimately the same error happens. This is pretty good evidence of a company with a terrible product that's going down in flames. No wonder the company's stock has tanked big time over the last year.
We're sorry to hear about the issue you're experiencing.
We would recommend starting with the suggestions available on the link posted by @RokuMary-F above. If still no dice, please reply here with the serial number of the affected Roku device. This can be found in the Settings menu by navigating to Settings > System > About.
