Describe the error

When I use the Tex function ,then put the error.After multiple tests, including reinstalling Texlive, cloning the source code, and modifying according to last month's issue report, I still cannot run the Tex function .

Code and Error

Code:

from manimlib import *
from os import system

class Example(Scene):
    def construct(self):
        tex1 = Tex("E = mc^2")
        tex2 = Tex("a^2 + b^2 = c^2")
        group = VGroup(tex1, tex2).arrange(DOWN)
        self.play(Write(group))
        self.wait()
if __name__ == "__main__":
    system("manimgl {}  ".format(__file__))

Error:

1. class Example(Scene):
   def construct(self):
   tex1 = Tex("E = mc^2", template="ctex")

   Write intermediate files to a temporary directory

   with tempfile.TemporaryDirectory() as temp_dir:
   temp_dir = temp_dir.replace(r"ADMINI~1", "Administrator")
   tex_path = Path(temp_dir, "working").with_suffix(".tex")
   dvi_path = tex_path.with_suffix(dvi_ext)
   ...

I solve it by this two change, but I don't know why.

I also have had this problem for months. It seems that the .tex file can't be written, so do the .log (by the way, it seems that the problem is still there, even if I have followed the changes)

[mryuans]

I have found a solution after checking the TemporaryDirectory class:

       ...
    # provide an actual directory
    with tempfile.TemporaryDirectory(dir=r"C:\tmp\temp_latex_base") as temp_dir:
        temp_dir = temp_dir.replace(r"ADMINI~1", "Administrator")   # <- it seems that this change doesn't work out my problem
        tex_path = Path(temp_dir, "working").with_suffix(".tex")
        dvi_path = tex_path.with_suffix(dvi_ext)
       ...

But the tex is rendered slower than other items (because I provided an actual directory to save the file? I'm not sure.)

Looking forward to a better solution.
