EDIT : It is a forge issue. Reverting to 30.0.42 resolves the issue. Leaving this so you know what the future holds.

Either update to 1.15.2, or downgrade forge to 30.0.43. Just before 1.15.2 some breaking changes got merged into forge, and I just directly updated to 1.15.2 instead of bothering to make a release on 1.15.1 and then 10 minutes later make another release for 1.15.2.

Did it through the lancher. Twitch is not showing 1.15.2. Thanks!
