2. Unity 2019.2.21f1
3. Android 4-11
4. Anyone device with android
5. Network - wifi 100Mbps
6. Any additional custom JVM settings used at runtime - no
7. Description issue:
The client connects to the server, enters the room, and after a while crashes. The amount of time from connection to crash is different with each new attempt.
Probably, this happens at the moment of receiving the next packet about the position of another player. If the client is alone in the room, no crash occurs.
Based on research, if you reduce the number of packets with a position to 3-5 per second, a crash does not occur (or does not occur for a sufficiently long period).
The crash doesn't happen when the client app runs in Unity Editor on PC. It occurs only on mobile devices on Android if the application is compiled in il2cpp (in the application compiled in mono, the crash does not happen). We did not build the application for IOS.
8. SFS configuration - in attachments
Some crashes (backtrace always empty):
