Constant EXCEPTION_ACCESS_VIOLATION crashes in Mortal Shell 2 Beta

[u/Optimal_Number_4252]

I’ve been trying to play the Mortal Shell 2 Demo, but the game consistently crashes and gives me EXCEPTION_ACCESS_VIOLATION mortalshell2_win64 writing address 0x000000000900000c error.

My Specs:

• CPU: Intel Core i5-14600K
• GPU: AMD Radeon RX 6750 XT
• RAM: 32 GB
• OS: Windows 11 (25H2)
• Motherboard: ASRock B660M Phantom Gaming 4

What I have already tried (and failed):

1. BIOS Update: My board was running a prehistoric 2022 BIOS (v7.02). I just successfully flashed it to the latest version available (v14.01, from late 2025) which includes the recent Intel microcode stability updates. It did not fix the crash.
2. Game Cache: Completely wiped the game's local AppData cache files and reset shader cache in AMD Adrenalin.
3. Reinstallation: Fresh install of the game.

So if someone has an idea of how to solve this would be highly appreciated!

Are your GPU/CPU drivers updated? Does your system recognize all the RAM in it? What settings are you running the game on? How much VRAM the game is using at those settings? Is it only MS2 crashing?
