I tested it first in creation mode with no problems, but when I used the datapack in survival mode after restarting my computer it didn't work. Is there something wrong with my datapack?

mc version:1.16.5Forge
BOT-main.zip

There are a few issues with your datapack.

1. If the datapack is a ZIP pack the initial BOT-main folder is not allowed and will prevent loading. If it's a folder pack and zipped for GitHub then it's fine.

2. The pack only contains a custom dirt soil. If you're trying to override the existing dirt soil the file needs to be in the exact same folder as the pre-existing one. data/botanypots/recipes/soil/dirt.json vs data/botanypots/recipes/dirt.json

3. The format of your dirt.json file seems to be using outdated properties. It should look like this.
