First of all, I hadn't noticed you mentioned you've got the Duo2 in the title.
Duo2 is surely able to bear also the last BH but the advice in my previous post might obviously still be followed, although is not compulsory as for other older models.
If the HDD is full it's easy to see...

You have every info you need in the Info submenus or, even, already when you enter the Rec List.
But if you never got any messages about the lack of space, this is not the poor windows, that need giga and giga of freespace! Your system does not work from the HDD (whom you might not even have, in theory).
Enigma2 images, like ours, run from flash: maybe you filled your flash with picons or else?
Check again your Infos to know how much flash space it's available,
Or, maybe the problem is that the HDD has too many defective sectors. If you have the Timeshift plugin and it's enabled, try and disable it and test your system without recording or playing any files, just zapping.
Then, step by step, you can test playing already recorded files, then recording again, then re-enabling Timeshift.
A test must be done isolating every possible causes, one by one.
Obviously, if you got a surely working spare HDD, you can try and connect it, formatting by the image and
mapping it (because in Linux systems it's not enough to format a device in order to be able to use it: it must be mapped. In your case as
/media/hdd/).
And finally, although you registered your account in this forum 7 years ago, it seems you haven't been reading our posts so much and, above all, you haven't read the rules, yet, specifically paragraph 4...
