EXCEPTION_ACCESS_VIOLATION (0xc0000005)

[DarthJahus]

Describe the bug

My game crashes with exit code: 0xc0000409 when in a specific place in my Minecraft server.

Vulkan does work on the same server if I'm using 1.21.5 with VIA. The server is on 1.21.4.

I have no idea how to debug this, but I'm willing to help.

• Minecraft 1.21.4
• Fabric API 0.119.4
• VulkanMod 0.5.6

Nothing else installed. No shader pack, no resource pack, no other mod nor library.

• AMD Ryzen 9 7900X3D 12-Core Processor
• 32 GB RAM @ 4800 MT/s
• AMD Radeon RX 7900 GRE 16 GB VRAM
• AMD Software 25.9.1
• Windows 10 22H2 (19045.5371)

Steps to reproduce

1. Enter the world
2. Be at or approach said place
3. The game crashes

This seems to be an issue in the AMD driver for Vulkan, specifically in the amdvlk64.dll driver, which is the AMD open Vulkan driver. I recommend you try updating your drivers, or maybe install Adrenalin driver from AMD

Tried driver version 22.04.2, 23.12.1 and 25.09.1. Same. I've tried all versions of VulkanMod from Modrinth. None of them works in that specific areae. And the issue is only on my PC, it seams.

My game (1.21.4) crashes when I approach a very specific area.

By setting render distance to 2, I could lower the radius and narrow down the area. It's really small.

I don't use server mods that force client mods, and I don't have texture packs installed (removed everything). I've even removed almost all server mods.

Really weird crash, overall. The problematic zone is like 2x2x2, only on my PC.

A guy on the Discord tried with his account, and a friend tried with the exact Minecraft instance (zipped, copied). They have no issue at all. I also changed my GPU driver to something older, same issue.
