Relevant Code:

It calls this code when resuming the app and crashes.

Hi @Cellaryllis – a fix for both the NPE and OOM will be going out in the next release. However, this issue has proven extremely hard to reproduce, so we’ve been unable to fully verify if the OOM is resolved, unfortunately.

I’ll update this thread again once the new version is released.
