I just uploaded a .ctf file on a local MATLAB Web App Server, but I take the following error while I try to load a neural network:

Class 'network' is an unknown object class or does not have a valid 'loadobj' method. Object 'net' of this class has been converted to a structure.

Any idea? Thank you in advance!

If you are attempting to compile code using MATLAB Compiler that calls load to load an object from a MAT-file and there is no indication in the code itself that MATLAB Compiler needs to package the code, the dependency analyzer may not be able to detect that it needs to include the definition of the class. In this case use one of the workarounds in the "Fixing Callback Problems: Missing Functions" section of this documentation page, as this workflow is described by the Tip in that section of that documentation page.
