Music disc writing fails when hosting to LAN.

[DillyzThe1]

When playing in a multiplayer server/world as a player rather than the host, or even in single player alone, you can write your music disc perfectly fine. However, if you decide that would like to host a LAN world yourself, you may not write music discs, despite the fact your friends are perfectly capable of such.

Version List:
VinURL v1.1.2
Minecraft v1.20.5
Fabric Loader v0.15.10-1.20.5

How to reproduce:

• Get a blank music disc.
• Open to LAN.
• Attempt to write to the music disc.
• Notice how it fails to make a sound or store the data, and the amount of components stays at 6.
  • Playing it in the jukebox will also cause the server to error out, duplicating the music disc if the jukebox is right clicked.

are other people on the LAN world required? i followed your steps but couldnt reproduce the issue.

After some testing, that answer comes down to a solid no.
Even having the Minecraft console open, no real error generates unless I put the blank disc inside of the jukebox, but that's a separate issue of not checking if no data was set prior to right clicking the jukebox.
I did, however, come into some confusing conflictions where it ended up seeming as if unwritten discs were problematic when on LAN, and not pre-written ones that I'd rewrite to. That's conflicting because I played with one of my friends last night, and the issue would occur regardless.

I did just manage to get it to randomly fail after opening to Ngrok, but after re-opening the world and re-opening to Ngrok and inviting my friend, it works again?? It's very inconsistent and I'll update you with any new information as I come across some.

I should also mention, given that it fails within the prompt, it fails with /vinurl set <link> as well.

Update: It seems to be random/delayed from opening to LAN?
Every time it occurs, I have LAN play open for a random amount of time. It also happens regardless of how much I actually play or move around. It doesn't even matter if my friends are on or not.
