What is the issue?

Yesterday I worked with ollama without issues both on a simple GPU in my laptop's CPU and on an nVidia Titan V attached as an eGPU.

This morning I installed the update to v0.18.2, and now the server will not start anymore.

I tried to roll back to 0.18.1 and 0.17 versions, to no avail.

The server log is:

I have the same exception as mentioned above on a slightly different setup: Win11 home with AMD GPU. I asked my Qwen-Coder about it and this is (part of) his repsonse:

The error you're seeing is a Windows crash (Access Violation) — specifically, a Exception 0xc0000005, which means "Access Violation" (you tried to read/write memory that you don't have permission to access or that's invalid).

Let’s break this down step by step, explain what it means, and how to fix it.

🔍 What the Error Means
Exception 0xc0000005 0x8 0x7fff2fd6cb12 0x7fff2fd6cb12
PC=0x7fff2fd6cb12
signal arrived during external code execution
0xc0000005 = Access Violation (trying to access invalid memory).
PC=0x7fff2fd6cb12 = The Program Counter (CPU instruction pointer) was at this address when the crash happened.
signal arrived during external code execution = This crash occurred in native (C/C++/Go CGO) code, not in pure Go code — so it's likely due to a low-level library or native dependency.
From the stack trace:

github.com/ollama/ollama/x/imagegen/mlx._Cfunc_mlx_random_key(...)
This indicates that the crash occurred inside a C function (mlx_random_key) from the MLX library, which is a machine learning framework optimized for Apple Silicon (M1/M2).

Maybe this helps someone to find a solution. Thanks guys :)
