It would also be helpful if you let me know if there are specific situations in which the error often occurs. For example) When you run it right after unlocking the phone, when you run it after using another camera app, when you use the app again after leaving it open for a long time, etc. - It happened when I just unlocked the phone and turned it on, or when I was watching a video on my Samsung and wanted to record my exercise.
