Unexpected Tex error: Xelatex error converting to xdv.

[CaftBotti]

@TonyCrane I don't know why. I suddenly can't use tex.(business as usual before) There are two main methods on the internet: in constants.py, set TEX_ USE_ CTEX change to True; Replace \usepackage[UTF8]{ctex} in ctex_template.tex to the second line. But both have no effect. When i enter the code:

class Story(TeacherStudentsScene):
    def construct(self):
        self.teacher_says(
            TextMobject("I will tell you a story.")
        )

It caused this error:

Qt: Untested Windows version 6.2 detected!
xelatex: Bad parameter value.
xelatex: Data: font_mem_size

Exception: Xelatex error converting to xdv. See log output above or the log file: c:/beibi/a/media/Tex/5c29580c7c3fcd49.log

No file "5c29580c7c3fcd49.log", but 5c29580c7c3fcd49.tex. I clicked it with TeXWorks and ran it, and business as usual! If i return to animation, it is still raising errors.

I installed CTEX, miktex and texlive and set correct paths, but no effect. How can i solve the problem?

I read #570, and the result is: seem to have no effect.
