Modpack crash on startup

[Stekra44]

Hello,

me and my friend, we wanted to play our old world in modpack called Gejmr's futurecraft 1.7.10 link: https://www.technicpack.net/modpack/gejmrs-futurecraft-updated.680660

and when he clicks on play button the modpack loads (on the launcher) than launcher closes and after like 4 seconds it pops up again as it was before launching.

he has rtx 3060 and intel cpu (i dont remember exactly which one but i can find it if necessary, but its new one)

we also tried different versions of java but that didnt help, i came through alot of posts and topics but didnť find any help,

thanks for any help.

also if you need anyting like logs or such i can send it here.
