1.15.2 has an optional license information. 1.16.3 requires that the license information be present in the toml. You can simply add license="" into your mods.toml near the top and that should fix it. You can view some licenses here.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.
Have you read what the logs say? If the message is the same as the other people above then solutions were already given. If the error message is not the same as above, i think you should make your own topic and provide debug logs
Is there a full tutorial on how to do this? I don't know where .toml files are, how to add/format the license bit appropriately... Why do mods need this, and will Forge be updating to automatically include it??
Curse/Overwolf: If you are using the Curse Launcher, their configurations break Forge's log settings, fortunately there is an easier workaround than I originally thought, this works even with Curse's installation of the Minecraft launcher as long as it is not launched THROUGH Twitch:
When you have an issue with your mod the most helpful thing you can do when asking for help is to provide your code to those helping you. The most convenient way to do this is via GitHub or another source control hub.
When setting up a GitHub Repo it might seem easy to just upload everything, however this method has the potential for mistakes that could lead to trouble later on, it is recommended to use a Git client or to get comfortable with the Git command line. The following instructions will use the Git Command Line and as such they assume you already have it installed and that you have created a repository.
player, I asked some other people and they said that I deleted an important file so I deleted everything mc and reinstalled then when I launch forge it crashes and when I downloaded a new forge file it says:
