The issue is as simple the title sounds, after downloading v6 of the modpack I'm unable to open/run it at all. I've checked task manager and it's not just starting and refusing to show up on the screen, it just plain isn't doing anything. I didn't have any issues with the modpack previous to v6 I.E. never didn't have any issues regarding the firewall or anti-virus so I don't think that could be causing it. And I don't have a log to submit since it's not even in-game related. However I'm still able to use a few of the older mods from v5.16 by just moving them into the 0.6 folder so it's not an immediate issue.
