Well, tested Vulkan on 5.6 and it seems to randomly crashes. (Never happend before in 5.5s)
I Adb the crash and this is what chatgpt said about the crash log;
You're encountering a **SIGSEGV (Segmentation Fault)** crash in the **`RHIThread`** (Rendering Hardware Interface thread) on Android, caused by a **null pointer dereference** during a **Vulkan descriptor set update** inside **`libGLES_mali.so`**, specifically:
#00 pc ... libGLES_mali.so
vulkan::descriptor_set::update_descriptor_set(...)
---
### 🔍 Key Points from the Crash Log
* **Thread**: `RHIThread` (used by Unreal's rendering backend)
* **Signal**: `SIGSEGV`, code `1`, fault address `0x20` (means `nullptr + 0x20`)
* **Library**: `libGLES_mali.so` → This is part of the **Mali GPU driver (ARM)**.
* **Callstack**: Begins from `vkUpdateDescriptorSets`, eventually hitting Unreal’s `libUnreal.so`.
SO I;m sure this is just another mobile bug that Epic will ignore. OpenGL is also bug, so honestly, we can’t really publish our game in either ways.
