Here's the error message

For me, the issue was that I wasn't in the model directory with my workspace. So first launch matlab and then have it open in the directory where your model is located or from where the code was made.
I've been using just the simulink model so the matlab wasn't inclined to tell me that I'm not in the directory of that model where there are possible external files needed to be loaded and linked with simulink. These external files were addressed with relative paths and so the matlab couldn't find them in the workspace default folder.

For me the problem was the path. One folder contained a #-symbol which caused the error. Even if the path is relative a # in the absolut path can cause the error. So with the comments in mind a list to fix the error:
  1. Check if the workspace directory is the desired one
  2. Try using the absolute path to the file
  3. Check the abolute path for any uncommon sybols (Spaces and Underlines work; # does not work)
