Thank you for your feedback. This could happen due to multiple reasons, such as background applications consuming system resources, which can cause the camera APP to close unexpectedly. To resolve this, it is recommended to clean up the background applications by closing any unnecessary APPs running in the background, as this will help free up system resources and allow the camera APP to function more smoothly.
Additionally, ensuring that your device is updated to the latest system version is crucial, as software updates often include bug fixes and improvements that address issues like these.
