@MouaadAbdelghafourAITALI I tried to downgrade the dependencies but not working. Can you share which version you are using for firebase messaging and firebase-auth — Akshay, Jul 08 '20 at 16:05
`implementation 'com.google.firebase:firebase-inappmessaging-display:19.0.7' implementation 'com.google.firebase:firebase-messaging:20.2.1' implementation 'com.google.firebase:firebase-core:17.4.3'` — Mouaad Abdelghafour AITALI, Jul 08 '20 at 18:53
@MouaadAbdelghafourAITALI by any chance, are you using One Signal ? — Gersard, Mar 17 '21 at 19:05
@Gersard, no I didn't use it, the issue is already solved months ago, just update the Firebase libraries — Mouaad Abdelghafour AITALI, Mar 17 '21 at 20:16

If you updated library and getting error then try below code.It is worked for me.
 
 implementation 'com.google.firebase:firebase-core:17.2.2'
    implementation 'com.google.firebase:firebase-crash:16.2.1'
    implementation 'com.google.firebase:firebase-messaging:20.1.0'

I experienced the same crash reports with firebase-core:17.4.4 , i downgraded it to 17.4.3 and they disappeared .

the crash wasn't systematic though, only during automatic testing as far as I know
