System.ArgumentException Only TrueType fonts are supported. This is not a TrueType font.
I am reading the error report sent by you, but this is an error generated by Windows.
According to this, it seems that the font is not a TrueType Font.
I think the file seems to be problematic because it is in ttf format, but it seems to be different according to Windows.
It is an error issued by Windows, so I do not know how to deal with it.
