Why is the Google Pixel-5 Camera the only Camera not able to work with the hybrid mobile app named Let’s Live?

My team and I have developed a hybrid mobile app named Let’s Live. All functionality is working perfectly on every single of the 15-20 devices we tested, both Apple and Android, with the exception of the Google Pixel 5 phone. Specifically the CAMERA. On the Google Pixel 5 that we have tested, over 20 times (after uninstalling, reinstalling, rebooting, etc.)….while in the app, when we attempt to take and post a photo, the camera takes the photo, but WILL NOT populate the photo to the app afterwards. We have exhausted everything within our knowledge by dozens upon dozens of hours.

Many thanks in advance.
