Hmm, can't you see my posting as of May 24 with the link to that
schematic?

The only link I can see on that post is carousel-design.

Maybe you could repost?

As advised; you should replace C6 - even if it isn't the culprit, it can
cause all manner of nasty things to happen.

I'd use a low ESR 105 deg-C part - and I'd put a MLCC on the print side to
take the edge off its ripple current - but that's just my own preference.
