That’s a shame you get an error. It Is quite good for me. There is also the original V1 version that you can try. It’s discontinued but may work: GitHub - e1miran/Now-Playing-Serato
I would recommend this as one of the best ones. It is called Unbox and is getting better with updates coming soon. The author is very active on the Denon DJ forum too so can help and hear it works better on Windows. Check it out below.
There is a lot of discussion about this over here: Stagelinq protocol API - #329 by erikrichardlarson . If you post there then maybe someone will be able to help you.
