Parameter name contains invalid characters - Where??

[CiroCardoso3v]

I am not sure why I am getting this error. The geometry doesn't have any weird modifier, the material is super clean with clear naming. But when I press render I get this error

[Arnold]: 00:00:04 5656MB ERROR | parameter name contains invalid characters: "usr_qANQR1DDDQQJAwKdoKvgk3r9qGDSQwHPqm+2i17hhGie4dxQdMI8HfG072Pkl4laxkGY6xng8zK78njaOJspZvrP6HXeJlbSjK5E9dGeEyCIgTllkiffkvI"

But like I said. Object name is clean, the same with the material and there is no Arnold Modifier with a displacement somewhere. So why am I getting this error?

I say that invalid/malformed data is being sent to Arnold.
Can you export that one object to an ASS file? Or delete everything else but it, so you have a simple scene that gives the same error?

There were some characters on the Objects Properties. Solved
