The "LinkAssemblies" task failed unexpectedly error XA2006

Question

I have tried to skip the System.Configuration package when linking but still no luck.

I can compile the code and run it without issue for debug but when I go to compile as release build - using linker (sdk assemblies only) this is what i get.

Here is the error:

Severity Code Description Project File Line Suppression State Error The "LinkAssemblies" task failed unexpectedly.
