Hello,

You will need to update the SDK to the latest version and check if the crash is still reproducible.

Besides that, we need more information from you:

1. The full stack trace, not only the Thread that crashed
2. Some snippets of your integration, especially your customisations
3. User flow, do you have any information on what the user was doing when the crash happened?

Thank you for the report.

Best,
Nuno
