Error 000372 in ArcGIS Pro 3.1

[YesimSungu-Eryilmaz]

I am trying to run multivariate clustering (K-means) tool in ArcGIS Pro 3.1 and I keep getting this error " 000372: Spatial Reference for output is invalid. Please update to allow output to become valid."

  My layer is projected. Any help would be appreciated.

Hello @YesimSungu-Eryilmaz , as a first step, are you able to update your ArcGIS Pro to the current 3.3.1 version ? If this is a defect, it may have already been addressed.

I did update it but still having the problem

Are you able to post a small sample of data, and some notes on how to reproduce the 000372 message ?
