Instances are just a Black screen [BUG]

[TimewarpDrive]

I downloaded the betacraft release on github (the one that specifies itself as being for the mac, I also downloaded the generalized one from the website and & [launcher-1.09_16-portable.jar]), I opened the launcher just fine, logged in, created the instance, and I got an instance thats just a black window. It never changes, nor loads, or closes (Same happens with the other version). I have minecraft installed (if that matters).

-MacOS 12.7 (macbook air 13' 2017)

• not sure, but it's the full release version closest to the top labeled as mac; also the general one linked on the website does the same. +[launcher-1.09_16-portable.jar]
