This same app was working perfectly fine while when app images and associated matlab files(.m) were in same folder, but with this version I am getting this above error while packaging the app, the app runs as expected with F5.

Hi Vinyas,

I just had a similar error today with R2021a and over 2 years after yours!

I think the issue is that within Package App, the Output Folder is set to be the same as one of the folders that has been set to be included in the App. Certainly when I choose a new Output Folder my problem was resolved.

I hope your haven't been waiting on this answer for 2 years.
