I am working on a project and the touchscreen buttons for it do not work. I would appreciate any help in solving this matter.

    This may be the most frustrating experience of my life, I seem unable to upload a video or photos, if necessary I can try uploading the entire code as a zip file

    This is usually a firmware or touch mapping issue.

    Make sure the HMI firmware and the ESP32S3 Arduino example come from the same Elecrow package. Mismatched versions often cause touch to fail. Reflash the screen firmware, then upload the matching example.

    Also verify the screen resolution and rotation in code. If rotation is wrong, touches will not register.
