GA4 Adding Custom Definition - Error Code 13 - google-analytics

Question

I'm trying to add a custom definition to one of my GA4 properties and I'm getting this error in the attached image. The weird thing is that I've been able to add the same definition in another GA4 property without issues.

I've added this same dimension successfully to other GA4 properties late last year, but now I cannot add this dimension to a different GA4 property.
