Description

System Information
Operating system: Windows only, mac/linux are unaffected.
Graphics card: Irrelevant

Blender Version
Broken: Latest Master + 3.1 (anything that has the freetype 2.11.0 libraries on windows)
Worked: 3.0

Short description of error

Blender crashes when selecting slight hinting in the text rendering user prefs.

Exact steps for others to reproduce the error

Edit / Preferences / Text Rendering / Hinting. Change "Auto" to "Slight" and you get an immediate access violation within FreeType's FT_Load_Glyph function

There is a section of their code where they do this...

if ( FT_ALLOC( metrics, writing_system_class->style_metrics_size ) )
        goto Exit;

But writing_system_class is NULL so it dies.

There is a table that is not being filled correctly due to a compiler quirk that is addressed in 2.11.1
