Hi, sorry about that! Could you post a screenshot of the port settings in KBonk as well?
Could you take a look at the other reply to see if yours is set up in a similar way? KBonk has settings for two different ports; if they're both set to the same number, it'll cause issues when two things try to use the same port at the same time.
If the "Browser Source Port" and "VTube Studio Port" in KBonk's settings are the same, please change the Browser Source Port to a slightly different number!
Yes, that's it! I can see that the "Browser Source Port" and "VTube Studio Port" are the same. Please ensure those numbers are different! There's two separate things trying to use the same port, which is probably what's causing the problem.
I should've added something in place to keep the same number being assigned to both, I'll look into that for the next update!
