Text renderer is not rendering the text

Hi there,
I have the weird problem, that the text renderer is not showing the text. Instead its just like is:

Has anyone an idea whats happening there? Everything else works fine and the BP does not show any kind of error.

Best regards

Hello! Is that error occured only for one font? What if you set default one?
