Link for that with any proof?
You know full well that's nonsense. I would be very surprised to see any North Korean involvement with regards to actual fighting until after the BRICS meeting is over if ever.
The Russians are pushing the Ukrainians' button and will make their claims look ridiculous if they never turn up and have any involvement. A real shitehouse move would be getting them training in Belarus, or set them up in a training camp in Rostov oblast or Krasnodar Krai - and then they are one drone or missile attack from giving legitimacy to the North Koreans getting involved.
Now would NATO or the EU do the same and put their troops in, in the same way knowing that any response to them getting hit could take it all the way to Def Con One? Probably not.
Rumours of a huge movement of missiles in Russia after a slowing down in their use preparing for a big strike on Ukraine's energy sector now the weather is about to turn. Also Pokrovsk not looking likely this year - I can't see them getting a toe hold there to make a winter campaign possible myself so I suppose that can be sold as a Ukrainian success.
As ever, a very critical time in this war now.
