    posted a message on mod wont run after clicking play on the mc launcher

    i made a modpack and i click play in curseforge and it takes me to the mc launcher but when i click play on the mc launcher it takes a second and crashes

    then it says crashed with exit code 1, ive tried allocating more memory but that doesnt work, i duplicated the profile to see if it was old mods that are no longer supported but it still didnt work
