If you have the same problem, you can refer to what I have tried out.

1Download font: First of all, you need to download the "Youset Title Black" font. You can search and download it on some websites that offer free commercial fonts. It is recommended to choose the official website or the recommended sources to ensure safety - 22-28. 

2Locate the folder: Next, in your game's root directory, find the path "game/gui/fonts/". If the "fonts" folder does not exist, you can create it manually - . 

3Put the font: Finally, place the downloaded "Yousu Title Black.ttf" file into the "fonts" folder. Restart the game and the problem should be resolved.
