Thanks. I have repro'd the issue (you can also install miktex on mac/linux) and the fix is not obvious :/

- Do you get the same error with the following?
from matplotlib import ticker
import matplotlib.pyplot as plt
plt.rcParams['text.usetex'] = True
plt.rcParams['font.family'] = 'serif'
plt.rcParams['font.serif'] = 'Times'
plt.figtext(.5, .5, "$-1$")
fig.savefig('test.pdf')- In either case, insert
plt.set_loglevel("debug")immediately after setting the rcparams and re-run the failing code. In the output you should see lines of the formDEBUG:matplotlib.dviread:Dvi: /path/to/.matplotlib/tex.cache/bd/69/bd69c059493a3cf42a641ebfa844039e.dvi(with a different filename). (If the code in 1) also fails for you it may be easier to use it as there will be fewer files to try.) For each such dvi file, try running from the terminal (not python)python -m matplotlib.dviread /path/to/the/dvifile.dviand post the output.

Updates: I created a pure Windows 11 virtual machine. And install MiKTeX and Miniconda 3 from scratch. The bug can still be reproduced.
Then, I tried TexLive, and it works. So the bug is that MiKTeX does not work well with Matplotlib?

Possibly, though we should still try to fix that! I suspect this may be due to misconfiguration on your side (so perhaps the fix would be a better error message), but will need to investigate more (likely not in the very short term).

I suspect this may be due to misconfiguration on your side.
For this, I created a virtual machine with VMware (to control variables, I'm even using the English Windows version instead of the locale one I'm on). Install MiKTex and Python with its official installer.
VMware reproduce steps:
- create Window 11 vm by its iso: https://software.download.prss.microsoft.com/dbazure/Win11_23H2_English_x64v2.iso
- install Python: https://www.python.org/downloads/release/python-3119/
- install MiKTeX: https://miktex.org/download
- check miktex updates and install updates
- pip install matplotlib
- python bug.py
