App troubleshooting error

Whenever my app loads,it gives me this error"Cogic_hym has stop"...i've searched throughout the code im not seeing any error.kindly help



FirebaseDB is experimental, so apps using it will maybe crash.

Also, do you mind posting your security rules? In your screenshot, the database indicates that anyone can steal, modify or delete data.

Evidence ?

In my experience the component has been very reliable
