Hi!
Since I upgraded from UE 4.21 to 4.22 I’m getting the following error:
Fatal signal 11 (SIGSEGV), code 1, fault addr 0x6888b608 in tid 16650 (Thread-2)
I’m testing on android 8.0.0, Samsung Galaxy S7.
The funny thing is: when I package as Debug or launch it from the engine the app won’t crash, only in the release version (otherwise it would be better :D).
Do you have an idea?
My project isn’t some heavy stuff (I get 60FPS), I implemented ads using the AdCollection library and Google Game Services.
Logcat outputs also some other informations:

I hope you can help me to fix that issue. The crash occurs between 1 and 3mins after start.
Best wishes!
