How to resolve an error: Exception caught while trying to run ArcSWAT: The type initializer for 'OSGeo.GDAL.GdalPINVOKE' threw an exception.

[hyhkong]

I have installed ArcSWAT3 (version 1.0.4), built against ArcGIS Pro 3.5.4. I have ArcGIS Pro 3.6.1.
It is added fine as an add-in, but when I launch it, I get an error message "Exception caught while trying to run ArcSWAT: The type initializer for 'OSGeo.GDAL.GdalPINVOKE' threw an exception."

I am sorry to tell you that this is a known problem with ArcGIS Pro version 3.6 which so far we have not been able to fix. Chris
