I’ve just put a new chain on my turbo bike which I have not used in about a year. The chain is now chunking/skipping on both the chainring and cassette.
I don’t believe it was doing this with the previous chain which was severely overstretched
First video: chainring, every few revolutions the chain doesn’t fit into the cassette and sits on top. It then chunks downwards
Second video: rear casette there is a similar sound but I can’t see where this is coming from
Thanks so much for any help
Can you help me workout what is happening with my drive train?

looks like you got worn chainring…
Need sound

All parts of a drive train wear. When a severely worn/stretched chain is ridden, it can cause the cassette and chain rings to wear to fit the stretched chain. When you replace with a new chain, nothing works right because the drivetrain in its worn state, works best with the older stretched chain. It does look like there may be a bent tooth on the chainring that is causing it to jump up. Check at the point were it jumps if the tooth looks bent at all
@00:13 the quick link seems not connected properly
It looks like your quick link isn’t fully on. [here is a video on how to do that ](https://youtu.be/VtPlvhmJ9Xw?si=_U89Kx3l7RAwgMEk)
You haven’t popped the quick link
Something either that chain, part of it, or the set up is well out of line so your chain is not engaging properly
