@Yevhenii_Markosh, this is strange… because the issue has been fixed already and exactly in this version of the SDK Push notifications causing a crash when targeting Android API 31+
Let’s try the following. Please write the backendless dependency this way:
implementation 'com.backendless:backendless:6.3.6'.
Make sure you update (make) ptoject after changing the dependency. And run your project one more time.

Marina
