My system settings are the following:

• Windows 11 24H2
• TeX Live 2024
• Manim CE 0.19
• PyCharm Community Edition 2024.3

I'd like to make Cyrillic texts work. To test the behavior, I have removed the \usepackage[english]{babel} line from manim\utils\tex.py, and then I've made this sample code:

from manim import *


class CyrCheck(Scene):
    def statement(self):
        testtxt = MathTex(r"Проверка русского набора на промежутке (0;1) в режиме математики.").scale(1.)
        self.play(FadeIn(testtxt, shift=UP))
        self.wait(6)

    def construct(self):
        cyrtextmp = TexTemplate()
        cyrtextmp.add_to_preamble(r"\usepackage[T2A]{fontenc}")
        cyrtextmp.add_to_preamble(r"\usepackage[utf8]{inputenc}")
        cyrtextmp.add_to_preamble(r"\usepackage[english,russian]{babel}")

        MathTex.set_default(tex_template=cyrtextmp)
        Tex.set_default(tex_template=cyrtextmp)

        self.statement()

# To run this scene, I use the following command in my terminal:
# manim -pql cyrtest.py CyrCheck

This is what I have after executing the command: The result

As you can see, Cyrillic letters do not display at all.

I've tried doing a full reinstall of TeX Live. Didn't work.

I've also tried executing mktexfm larm1000 and then updmap-sys. Didn't work.

I don't know what to do. Will you explain why does it happen and what steps to take to fix it?
