My own mod keeps disabling after leaving mods list (My first mod)

[Groftin307]

So, I'm creating a mod for Don't Starve, and I've run into a problem. Initially, I used a YouTube tutorial, creating folders and files in the Don't Starve Together Steam directory. Then, after quickly looking through the tutorials that I was going to watch, I realized that this wasn't the topic I needed. Then I found a tutorial on Steam, in the form of mods for Don't Starve, which contained text files explaining how to create a modification on the topic I want. I want to create a mod that adds a new creature that performs various actions and affects the in-game world.
So, here's the problem: After I moved the mod file (which I originally created in Don't Starve Together, where it worked fine) to the Don't Starve mods folder, when I check the box next to it, that is, turn it on, and after exiting the mod list and returning to it, the checkbox is no longer there. I asked ChatGPT for help, and he did send me the fixed codes for modmain.lua and modinfo.lua, but the problem with disappearing checkbox ain't fixed.
