I used to be able to interact with the app designer after launching the app Im working on, but now it isn't working anymore. I tryed different apps/MATLAB versions, and it doesn't work whatever combination I use. This way I am not able to debug the app propertly.

For a better insight, when I Run the app and then try to click wherever on the app designer I get a warning sound and Im unabe to do anything there untill I close the App.

Many thanks.

Hi Jaume,

I understand that you are having a trouble opening with App Designer even after trying different MATLAB versions. There are some troubleshooting steps that you can try:

Check for antivirus software or conflicting software which may block App Designer from running properly\
Update your graphics card driver and make sure it is up to date. Graphics card supporting OpenGL 3.3 with 1GB GPU memory is recommended and an outdated driver may cause issues with App designer. Please check your version using opengl command to verify your graphic card version is compatible with above requirements.
Run MATLAB as an Administrator. This will give you MATLAB full administrative privileges, which can help resolve issues with App Designer. Please refer this link for more information.

If all else fails, you may need to uninstall and reinstall the MATLAB. This will remove any corrupted files that may be the causing the issue with App designer.

Thanks
