I have a recurring error when I try to do the Ordinary Least Squares (OLS)

[EduardoAires]

Hello guys, I was doing some Ordinary Least Square's for my college work. My project has alot of shapefiles and tables in it, I dont know if that can cause this type of issue. It appears that error in the screenshot, it's strange because technically the operation is executed, but the shapefile doesn't appear in my contents pane, but it appears in the folder I told him to save. I don't know if I can trust this results or not.

I closed and opened ArcGIS Pro but it didn't resolved anything, I even tried to restart my pc but once again didn't work. If any of you know why this is happening I would appreciate.

Best regards,

Eduardo Aires
