Issue with GWR

Hello Community!

I'm currently trying to work with some regression analysis with census data.  I run the OLS analysis for my dependent variable using 5 explanatory variables.  I then moved on to GWR using the same dependent and explanatory variables.  The problem is that I get an error continuously when trying to perform the GWR analysis.  It appears that GWR does not like one of my explanatory variables (Edad - age in Spanish).  I checked the VIF values after running the OLS and all value are way below 7.5.  I created thematic maps of all the explanatory variables.  Perhaps age and distance to coast show some degree of multicollinearity, however, this collinearity does not continue throughout the entire study area.  I am attaching a document with all the images and the error. 

Any help regarding this issue will be greatly appreciated.  Thank you so much for your time and feedback.
