Found out that Matlab may have including the Startup file in the current directory that was being used for MATLAB. At first, it seemed like MATLAB message was refering to a separate startup file for the standalone app. However, when finally used MATLAB R2018b which provided more clearer error:
- Undefined variable "at" or class "at.mep.Start.start".Error in startup (line 10)Undefined variable "at" or class "at.mep.Start.start".
This line was only in the MATLAB IDE, why should MATLAB include this startup file or rather not make it an option.
- The solution was to simply remove the startup file.
