OutOfMemoryError crash on GrapheneOS

Recently AirGuard started crashing with an SQLite OutOfMemoryError on my GrapheneOS Pixel 4:

I'm not sure yet, but it might be related to placing it on the wireless (Qi) charging dock (Anker PowerWave Stand).

These issues are very hard to debug on Android. Almost all crashes we get in our crash logs are Memory related. If anyone has good ideas how to identify which parts might cause this, we are open for help here

We should try using LeakCanary to find the probable cause of the leak.

I already used LeakCanary to look for memory issues, but nothing special was reported that I could act on. These memory issues are quite hard to catch.
