hugo serve -D works fine.

This looks related:-

Everything was fine, then decided to upgrade to your latest version. This was tricly as had to copy in the shortcodes, etc. So maybe it's an error my end. Any help in resolving would be good.

build and server work on my machine™. Make sure to run on Hugo v0.69 and upwards.

hugo version reported 68

upgraded to latest 0.70 and all okay - I think you need version0.69 for PostProcess to work:-
