これについては調査する予定です

申し訳ありません。
上記内容につきましては、自己解決しました。
古いアバターだったため、Atatar descriptorが問題だったようです。
既存のAtatar descriptorゆ削除したうえで入れ直したら起動しました。

わかりました。しかし、MA側にバグがあるのは変わりません。上記のスタックトレースで十分調査できると思いますので忘れないようにここまま開いたままにさせてください。

Howdy! I also ran into this error on my Kikyo avatar, and the issue ended up being with the Playable Layers dictionary.

As you can see, I don't have an Action layer slot, but instead two FX layer slots. So, when searching for the Action layer in the dictionary, the key did not exist.

To fix this, I hit the "Reset to Default" button and re-assigned the layers. This could also be fixed on the plugin side by checking if the key exists before performing the MA Merge Animator.

Hope this helps resolve the issue! And here's my Stack Trace before I reset the layers:

Thanks! This might still need to be an error, since the avatar descriptor is corrupt and it’s not clear what to do if eg there are two FX layers… but at least it can be one that is more clear about what is wrong.
