Question

My app works perfectly fine both in debug and release mode. But in Google play store vitals section there are 3000+ crashes reported within a weeks time with stacktrace as shown below. I am not able to understand this log so as to locate the reason for so many crashes for almost every devices as reported in play store console. Kindly help.
