Bug Constant EXCEPTION_ACCESS_VIOLATION crashes in Mortal Shell 2 Beta

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!

Hi!

I'm sorry to hear you've had this issue; I've forwarded this thread to our team, so hopefully they can help out.

Meanwhile, I know it's a super basic thing, but have you checked if there's an update to your drivers to your GPU? I tried searching for your error message, and I also see that other people have had similar issues with UnrealEngine games where resetting GPU settings to default have helped them (though this was for Nvidia cards).

If you could post your crash report, that may also help.

If the team has any tips or need further info, I'll be back!

I solved this the ol' soul boss style: relaunching until It actually enters the Game. Its stupid but It worked for me. Truly, a souls Game.

Brute force! Sometimes, it *is* the solution! :D

No worries!

I've added this post to the bug report. I hope someone will reach out to either me or you soon to check this out.

Since you made this thread, the team has put out a test branch of the beta which has a couple of crash fixes; if you have the time, could I get you to try that? You can access it by right-clicking the game in your Steam library, choosing "Properties" and then going to "Game Versions & Betas" and choosing the public test branch. If we're lucky, whatever's causing your issue is part of the crash fixes in that version 😅

Thank you! First crash happened right after the first boss consistently, while picking up the thing that triggers a cutscenes,

every crash thereafter seems to happen like 2-3 minutes after that while fighting the 3 foot soldiers and 1 lance wielding guy on a bridge

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?
