Creating a new VRC Expression Menu Causes Inspector.InitOrRebuild to appear and Causes Editor to hang/crash

Pretty much as the title states. im not entire sure when the issue started but ive completely lost all ability to create a brand new VRC Expression menu. the project in question has all vrc sdks up to date (3.10.1). heres basically the breakdown:

  1. I right click and hover over Create>VRchat>Avatars>Expressions Menu

2. On clicking Expressions Menu the editor freezes for a moment and then a window pop up showing “Inspector.InitOrRebuild Waiting for unity code to finish exectuting”

and then nothing. Ive let it run for 30 mins with no change. In Task Manager it shows the Unity editor is not responding. forcing me to end the task and lose all progress made on whatever i was working on.

currently on another project (which is way larger size wise and age wise) I can make a menu as normal. so im not exactly sure whats going on.

Edit: existing expression menus work fine, its only when i attempt to make a new one does unity hang

I know this is late (my account got put on hold) but after much testing the issue was with an avatar in the scene, specificly one of the menus on it, after removing that from the active scene everything functioned normaly. Hope this helps those who experence this.

Glad you were able to at least post something now. Looks like you are on the ball with this one

I did a bit of digging into the menus to see if the entire menu is bugged or a single menu item is causing everything to break. In which case I found that a single menu item (in my case being the Momoko Goat by RPGSlayer) caused the entire issue.

the only problem is, this issue cant be replicated easily as in the time since I originally posted till now, I made an made another project and copied everything over (like ctrl-c ctrl-v). And to no surprise, the bug didnt happen again.

But the TLDR for anyone else that comes across this issue:

  1. Find out which avatar is causing the bug.
  2. Find out which menu is causing the bug.
  3. Remove the toggles of the affected menu till the bug stops happening.
