i had the same exact issue with 2 ROKU tvs in same household - nothing was changed on either TV both TVS the cable stations disappeared. I believe due to automatic software updates
after complete factory reset and NOT connecting the internet and all the channels were restored and running well I allowed the ROKU TV to work without issue for over 2 hours. Then i connected to the internet and right after the ROKU TV updated everything, all the missing channels were missing again. Once again this is clearly a software issue from ROKU... please try what i described in your labs and the problem will be obvious.
FIX IT ROKU - just go back to the last version of software that worked! Then redo the update correctly
