The program cannot find the tex log file

### Describe the bug
This problem was encountered when running the GraphExample code in the official document（ https://3b1b.github.io/manim/getting_started/example_scenes.html ）。 The bin folder path of Letex has been added to the system environment variable, and Miktex has completed all updates and installation of all packages.

**Code**:
sin_label = axes.get_graph_label(sin_graph, "\\sin(x)")
relu_label = axes.get_graph_label(relu_graph, Text("ReLU"))
step_label = axes.get_graph_label(step_graph, Text("Step"), x=4)

**Wrong display or Error traceback**:
