TL;DR

The most likely fix is to remove or disable the Apple-specific code bundled into the Windows build of Ollama, specifically the MLX imagegen module, which is causing an access violation on startup.

Guidance

• Identify the MLX imagegen module as the source of the crash and investigate its compatibility with Windows.
• Check if there are any configuration options or environment variables that can disable the MLX imagegen module on Windows.
• Consider building Ollama from source with the MLX imagegen module excluded or disabled to test if this resolves the issue.
• If possible, try running an earlier version of Ollama to see if the issue is specific to a recent change or update.

Example

No specific code example is provided as the issue seems to be related to a build or configuration problem rather than a code snippet that can be easily modified.

Notes

The exact steps to disable or remove the MLX imagegen module may depend on the build process and configuration of Ollama, which is not fully detailed in the provided information. Additionally, without knowing the specific version of Ollama, it's challenging to provide precise instructions.

Recommendation

Apply a workaround by disabling or removing the MLX imagegen module, as it appears to be the cause of the crash on Windows. This approach is chosen because the module seems to be Apple-specific and is not compatible with the Windows environment.
