Hello,
The user claims to have narrowed down the issue to specific objects containing image sequences. Removing these image sequences from the affected objects allowed the application to build successfully.
When your export for Android or iOS fails in Construct 3, note the error message.
Start removing objects from your project one by one and attempt to build after each removal. This helps pinpoint which object might be causing the problem.
If removing an object allows the build to proceed, check if that object uses image sequences. Image sequences are animations created by displaying multiple images in rapid succession.
If the object uses image sequences, try removing them and replacing them with single images or explore alternative animation methods.
After removing the image sequences, attempt to build your project again.
