Avatar Help!! [Rurune]

[Gummy]

Hello~~ I am trying to upload the base Rurune model (v1.0.7) no editing but I keep encountering this error. BOOTH

I saw this thread --> Avatar Help! of someone encountering the same error and I followed what they said in the thread but it is still not working for me.

[Changed SDK to 3.5.2 and changed to Unity 2022.3.6f1]

Could anyone help me with this issue? Any help would be appreciated T_T Thank you~~!
