Why do I see the error message "Unable to resolve the name coder.loadMatObj." when doing code generation with Deep Learning Toolbox block inside in R2020b?

When trying to generate code of Deep Learning Toolbox blocks in Simulink an error shows up and it does not say, how to resolve it.

The full error message looks similar to:

"Unable to resolve the name coder.loadMatObj. Function 'Predict/MLFB' (#80.48.173), line 2, column 11: "deep.blocks.internal.deepNetwork({in_1}, {size(in_1)}, 'untitled/Predict', 'D:\w"
Component:MATLAB Function | Category:Coder error
Errors occurred during parsing of MATLAB function 'untitled/Predict/MLFB'"
