Have you sent that link to Stephen at Fibrelyte? Possibly they have made a 3/32" track ring for you, if you asked for 3/32" single without specifying that you were using 1×9/10/11. The teeth would be 2.4mm wide for 3/32" but 2.2mm for 9/10/11-speed. Everything I've ever had from them has been spot-on dimensionally, but somebody may have erroneously sent the wrong G-Code to the CNC, either due to confusion about exactly what you were asking for or just dumb error.

Yeah, I've sent it to him but no reply yet.
Hmm, that might explain things but it's a bit too late to change now. Bugger. -
"just watched the video, it's definitely something to do with the interface between the chainring and chain. No idea why but the chain seems to be 'popping' onto every tooth. My first reaction is the chain is too narrow for the teeth but the chain is sitting on the teeth once it's 'popped' and located so I can't imagine it's that. Next thought is are the tips of the teeth chamfered to allow the chain to slip on, but I'm sure they are. What chain is it and just out of curiosity, is the chainring sitting completely flat on the feet or the crank spider i.e. it's not tight on the crank and sitting at a very slight angle or even being forced to bend? The best way to work that out is to untighten all the chainring bolts and see if the chainring moves at all. I'm clutching at straws a bit as it's not something I've seen before but it does look a bit like the chainring might not be running true."
He suggested not using it. Le whoops. #fuckit
