MATLAB: Problem with Matlab Standalone Application

MATLABMATLAB Compiler

Good morning to everyone.
I have developed an application in Matlab appdesigner but unfortunately at the time of exporting it as a desktop application, it doesn't work properly and I think it's because it's not exporting certain functions ("cell2sym, solve, str2sym, subs, syms") that I use in my code. How could I fix it? Make use of those functions frequently in my code. Thank you !
mcc -o ShaftDesign -W 'WinMain:ShaftDesign,version=1.0' -T link:exe -d D:\Programs\Matlab\AppDesigner\Tesina3_1\for_testing -v D:\Programs\Matlab\AppDesigner\Tesina2.mlapp -r 'C:\Program Files\Polyspace\R2020a\toolbox\compiler\resources\default_icon.ico'

Either remove the file or function from your code, or use the MATLAB function "isdeployed" to ensure the function is not invoked in the deployed component.
