[🐞]: MouseClicked event handler crash when leaving multiplayer server

[Dayceiver]

Before Continuing:

• Check you are using the latest version of the mods and its dependencies
• Always include a latest.log if you are crashing
• Remove mod that enhances Minecraft: Optifine, Sodium, others. The issue persists.
• If you are unsure which mod is the culprit.
  Disable all of your mods and enable them 1-2 mods each time to isolate the culprit
• Confirm that there is no existing issue with a similar description submitted in the list of issues.

Version

1.21.1-FABRIC

Supplementaries Version

supplementaries fabric 1.21-3.0.40-beta

Moonlight Lib Version

moonlight fabric 1.21-2.17.32

Describe Issue

I was getting the relatively generic mouseClicked event handler error as seen below whenever I disconnected from a multiplayer server that I'm hosting. After trial and error, removing mods one at a time on client and server, I determined that the Supplementaries mod was behind it.
Not sure what could be done. I hesitate to try loading older or different versions of supplementaries to see if they'll work instead, but either way, figured I'd report the bug. Please help. Plz, I'm begging you.

Oh also, the "legendary tooltips mod" will crash your game if the flute item is on screen. Just fyi.
