Get an error when opening a library changing something and saving it - unfortunately the error is only occurring from time to time so it is almost impossible to troubleshoot because I cannot reproduce it reliably. Any guidance on how to find the root cause of the issue?

The block name has to be a valid MATLAB name. Make sure it follow the naming conventions.

Note: Make sure the name of the library(valid name) you are trying to save does not have space at the beginning or at the end of the library name. That is why it’s always a good idea to run Model Advisor checks.
