Crashes trying to convert an image

[pf56]

I'm trying to use the ImageConverter to convert a website to an image, but the application crashes. This might be an issue with libwkhtmltox itself, but I figured I'd raise the issue with you first.

Running on Windows 11, using .NET 6, WkHtmlToX v6.0.0 and WkHtmlToX.native.win.x64 v0.12.6.

Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I will check and get back to you

Indeed there is something wrong in native lib - I will need to remove this functionality
