The installer doesn't download libraries if they're already present or not required on the client/server (depending on which one you're installing). There are no errors in that log, everything appears to have worked correctly.

If Forge is crashing, post the FML log (logs/fml-client-latest.log in the game directory) in a spoiler (the eye icon in the post editor).

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

You're running 1.12.2, but you have a bunch of 1.7.10 mods installed; which won't work. Mods (especially coremods) only work for the Minecraft version they were built for.

You should use a separate game directory for each Minecraft version so each version has its own mods, config files, etc.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

Failed loading villager cartographer registered at cartographer - frozen tick

Allocated 10 Gb of ram. Could try again with more but I read using too much can slow things down as well. Going to try another big modpack and see if i can replicate the problem. It seems like this cartographer problem is kind of popular and doesn't have a solid solution yet, but i suspect its some generation mod since it's a crash that happens when specific chunks are being loaded. so i'll still try to lookout for what mod it could be as i add. i'll report back after testing as you suggested for a bit

Failed loading villager cartographer registered at cartographer - frozen tick

I have no idea - is enough RAM allocated?
Do other pre-configured modpacks work? Maybe use such a modpack as working base and add new mods one by one
