Bug Report: Bug Report: Incorrect LaTeX Formatting for Mathematical Formulas

`Steps to Reproduce`

A recent issue with the LaTeX formatting in ChatGPT's responses. Over the past day, mathematical formulas are being generated with non-standard delimiters, which prevents them from being rendered correctly in Markdown editors like Typora. It's important to note that all mathematical formulas render correctly within the ChatGPT web interface.

`Expected Result`

Inline formulas $...$ or \(...\).
Block formulas $$...$$ or \[...\].

`Actual Result`

Inline formulas are now enclosed in (). For example, (\epsilon\ge 0).
Block formulas are now enclosed in []. For example, [x_s=Ax_s+Bu_s].

`Environment`

Chrome
