**What Game**
Elden Ring (Shadow of the Erdtree DLC)
Storefront link: https://store.steampowered.com/sub/1010506/

**Describe the bug**
The base game runs perfectly fine without any crashes in any other area. However, the crash is completely exclusive to the DLC. Upon entering the DLC area ("Shadow of the Erdtree") and advancing just a few steps forward, the game immediately crashes back to the Gamehub launcher.

**To Reproduce**
Steps to reproduce the behavior:
1. Launch Elden Ring.
2. Enter the DLC area (Shadow of the Erdtree).
3. Walk a few steps forward.
4. See error (Instant crash to launcher).

**Expected behavior**
The DLC area should load, render, and play normally without crashing, identical to the base game performance.

**System information:**
- OS: Android (RedMagic OS)
- CPU/SoC: Snapdragon 8 Elite Gen 5 / REDMAGIC RedCore R4 (16GB RAM)
- Video driver version: StevenMXZ Turnip Gen8 V31 (Experimental for Adreno 840)
- RootFS used: Gamehub Integrated RootFS
- FEX version: Fex_20260509 (Gamehub build)
- Thunks Enabled: Yes (Managed by Gamehub)

**Additional context**
- Is this an x86 or x86-64 game: x86-64
- Does this reproduce on AArch64 with Radeon/Intel/Nvidia: Untested
- Is this a Vulkan game: Yes (via VKD3D-Proton 3.0b)
- If Yes, What is your Vulkan driver: StevenMXZ Turnip Gen8 V31 (Mesa/Turnip)

Add any other context about the problem here:
The game is running inside the Gamehub emulator environment on an Android device. It uses proton10.0-arm64x-2 as the compatibility layer and vkd3d-proton-3.0b to translate DirectX 12 calls into Vulkan. The crash is entirely specific to the Shadow of the Erdtree DLC area.
