downgraded from 24H2 to 23H2 just to use mesa, was worth it for me but I don't recommend it at all since it could just auto-update again to 24H2 and mesa v2 will be coming soon. better just to wait.
bro i saw youre message, if you have windows 11 24H2 it wont work, im having the same issue. im just waiting for it to release because i have lifetime, if you want it now, it would say watch a youtube tutorial on how to downgrade to 23h2, or wait on the mesa v2 update.
