Hey Ethan,
I understand that you are facing an issue where Chinese characters are being displayed in several places in the MATLAB UI.
Please try the following workaround that may resolve the issue:
Verify whether any other languages are listed in the "Language & Region" section within the system preferences on your Mac machine. Set "English" as the primary language in the "Language & Regions" settings. If any secondary languages are present, please remove them.
You can look at the following MATLAB Answer for more details - https://www.mathworks.com/matlabcentral/answers/2042597-why-do-some-text-parts-of-the-macos-matlab-r2023b-ui-appear-in-chinese-language
I hope this helps!
