Description

Hi everyone, since the last windows update Quicklook stopped working and I keep getting the attached msg every time I launch it:

03/06/2025 12:16:06 Windows 10.0.22631.2

System.IO.FileLoadException: Could not load file or assembly '0Harmony, Version=2.3.6.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Invalid pointer. (Exception from HRESULT: 0x80004003 (E_POINTER))
Filename: '0Harmony, Version=2.3.6.0, Culture=neutral, PublicKeyToken=null' ---> System.ArgumentNullException: Array cannot be null.

Is this error related to the app itself or is it something on my side? I hope this helps either way.

cheers

Research direction

Start with QuickLook.Helpers.MessageBoxPatcher.Initialize and the Costura.AssemblyLoader.ResolveAssembly path shown in the stack trace. Reproduce startup on Windows 10.0.22631.2 and determine whether the embedded 0Harmony assembly can be loaded; done means QuickLook launches without this FileLoadException.
