It worked! Thank you so much for your help. I feel like a huge weight has been lifted off my shoulders. I can't thank you enough, What you did was really helpful. I've given you full credit for your contribution and for helping me out.
However... there's one more problem I haven't been able to fix. It's not a major issue, so you don't have to help if you think it's too much trouble. The icons on the main menu screen are overlapping or not displaying correctly, and some are missing. I think the cause is the same as before: the Thai language and the font I'm using. As for the missing icons, I think it's because I translated some of the English text used in the code or some plugin. Even though the icons are missing and the menu overlaps, all the functions still work normally without any problems.
Lastly, I'd also like to support you by purchasing your mod for 5€ as a token of my appreciation. I'll also promote your mods in the Thai community. They might like your mod too. Who knows, maybe we'll cross paths again in the future. (when I'm stuck on another modding problem, haha)
