I have installed ATM 7, the launcher opens correctly, but when I try to open Minecraft it doesn't open and automatically closes Minecraft and gives me error code 0 from the launcher. I have reinstalled the mod pack and reinstalled Minecraft and nothing changed.

what's your java version?

I have fixed this by unintsalling all java and minecraft. Restarted the pc, installed Java SE dev kit 17 and ran curseforge. Then it launched for me. This also fixed the cant create virual machine issue.
