When I load the modpack it does it correctly but when it gets to the main menu non of the buttons work and it seems that they're not even recognized as buttons due to when I hover them nothing happens, i have half of my ram available so I don't understand why. I even repared the minecraft installation.
I have ryzen 7 5800H, RTX 3060 6gb, 32gb of ram.the only exit code I could have is 1. Thanks for your efforts

I fixed it, I had to reinstall the modpack, updating it was the issue.
