I’m using Godot on mobile, and I keep experiencing frequent app closures. Even with small projects and no visible freezes, Godot suddenly shuts down and won’t reopen the project unless I first enter recovery mode and then exit it. This shouldn’t happen in projects that only contain standard 3D nodes. The issue usually appears right after performing some action.
It is unlikely that someone on Godot forum is in position to help you with an android problem, even if it involves Godot. You will need to investigate first what exactly is happening. Is it a crash? Is it an out-of memory situation? Is it project specific? Is it device specific? etc
You can begin by testing a range of projects on a range of devices. Also get and study the log from the device.
