Masive error after updating to Firebase Crashlytics SDK

问题

I recently upgraded my app to Firebase Crashlytics SDK following this guide (https://firebase.google.com/docs/crashlytics/upgrade-sdk?platform=android) . I tested it and it worked properly so I uploaded it to Google Play.

The problem is that I am receiving many error reports from my users since then. The report is as follows:

 java.util.concurrent.RejectedExecutionException:

  at java.lang.Thread.run (Thread.java:919)

I have only made the changes that appear in the guide so I do not understand why I am receiving that error if I have not modified anything other than the syntax to that of the new SDK.

The error report does not refer to any point of my app so I do not know what may be happening. I have searched the Internet and can not find information about it. Any ideas?

Thanks.
