Looks like an issue with BetterMinechafts, check for an updated version and if there isn't one report this to them.

Try unplugging the gamepad

Try deleting C:\Users\Norman\AppData\Roaming\.minecraft\libraries\net\minecraftforge\forge\1.16.4-35.1.4\ and reinstalling that version of Forge, or try a newer version.

Try Johann Löfflmann's JarFix utility.

Yes, that handles the first character... there are requirements for the others...

Re-read what I already said

Please provide debug.log (more info on where it is and how to provide it in my signature below, just expand the spoiler)

Your mod ID needs to match the Regex pattern described in this error, which can be broken down as follows: first character needs to be a lowercase letter, followed by between 1 and 63 characters that can be lowercase letters, numerical digits, underscore, and hyphen.

We don't provide support for things that are so easily made into (and are indeed already used in) cheats, sorry.

Delete C:\Users\lawat\AppData\Local\Temp\forge_installer8667655478790341714 and C:\Users\lawat\AppData\Roaming\.minecraft\libraries\net\minecraft\client and try again.

This also makes things inflexible as now any item you make with that class can't go in any other group

The installer is an executable jar file, something you run. It's not something you extract and look for a readme in.

First that's not how you run a Forge server, that file starts a vanilla server. Second, try running the jar manually via the command line and see if it spits out any errors.

This has been discovered to be an issue with M1 Macs where Apple decided to change their graphics API and not provide backwards compatibility
