Logs are below, I tried to debug this for a while, and would really appreciate any direction in what mod(s) could be causing the problem. It's only when certain chunks are being loaded that this error comes up and soft locks the game, and the tick freeze is always preceeded by this villager error. Thank you!

Same issue without distanthorizons?

Yep, same error unfortunately.   

Also make a test without Embeddium/Oculus, Modernfix and immersive_optimization

Remove these one by one - start with immersive_optimization

If there is no change, add the new crash-report or log

No change unfortunately, tried with just one removed, then all. Here's the crash log for all of those mods removed. Thanks again!^^

I also just tried with iron's spellbooks removed, since that seemed related, but i am still having the same problem, even in newly created worlds. https://mclo.gs/AtrAfaj 

Also make a test without jeresources and jei

no change, thank you for the patience ^^

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

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
