the VRC Avatar Throwing the Excepetion IS public, https://bestboivrc.gumroad.com/l/HXzlU (its listed but free.) and seems to be throwing it when detecting Expressions.

I downloaded the unitypackage from the URL you provided, opened “Chibi - PC Setup Scene.unity” and tried to convert “Bestboi Chibi Base” to VRM, but no exceptions occurred.

The unitypackage is huge, can you provide a minimum unitypackage that can reproduce the problem?

im away from the PC at this evening, (sorry i didnt see this till now, the email notifcation got burried! ) i'll try but it was sporatic with the converter within Unity, and when it didnt, it'd result w/ no errors but still a broken output for VeeSeeFace/even the mod for VRM Models in Valheim

If you are having problems with apps, please contact that apps.

@CaelThunderwing Does “NullReferenceException: Object reference not set to an instance of an object” still occur?

There is no reply, so I close this.
