If you believe it's lack of cooling (stock cooling of Bolts DOES suck, runs too hot), then take steps to have it run cooler like I suggested at TiVo offering Bolt Vox to replace Roamio Plus and many other places.
My never been opened 3 TB Bolt+ w/original stock drive from April 2017 still runs fine. It runs 24/7 and I have all the power saving/management features disabled.
I used to keep it cool w/laptop cooling pads with fan(s) in them. Now I use those two AC Infinity fans. If you want to start w/o spending too much $, I think you should start with MULTIFAN S4, Quiet USB Cooling Fan, 140mm and stick some rubber feet under it to raise it a bit more if it's on top of a surface w/no holes in it. You can run it faster w/higher voltage with their 6.5 volt AC INFINITY, Turbo Fan Power Adapter.
If you wish, you could then later add [IN STOCK ON AUGUST 25, 2020. NO PRE-ORDER] MULTIFAN S2, Quiet USB Cooling Blower, 120mm.
Streaming providers will almost certainly not allow recording of streams due to licensing and DRM reasons. I wouldn't hold your breath for that.
As for new apps, I also wouldn't hold your breath for that, unfortunately. I'd look to other popular boxes/sticks w/growing users bases for that, unlike TiVo.
