Avatar Tools Tab Shows Up Blank

[N1Chris]

I have imported Pumkin Tools v1.4.1 from the VCC repository with Unity 2022, and the Avatar Tools section of the asset only shows a blank window when selected.

I have done the following, in order:

1. Closed the window and reopened
2. Closed the project and reopened
3. Readded the asset completely
4. Reimported the entire project entirely
5. Tested on a separate project

All other sections such as the Pose Editor and Texture Packer show up and work as intended so it's importing okay. What else should I be doing?
