I had the same symptom. I discovered the malware "PremierOpinion" in my Systemtray and deinstalled it. Solved it for me.

I discovered the malware "PremierOpinion" in my Systemtray and deinstalled it. Forge does not freeze any more.

MC 1.12.2, Forge 14.23.2.2618 (also had this problem with ...2611) I renamed .minecraft to start with an empty dir, reinstalled MC, started vanilla, installed forge*, no mods or anything yet, created a new profile, started it: Forge freezes "when the hammer starts to go down the second time". Last line in fml-client-latest.log is "[main/INFO] [FML/]: Starts to replace vanilla recipe ingredients with ore ingredients." Just as in this thread. No ideas there. What can I do? *= I had to do for Forge installation: ... otherwise I got "These libraries failed to download. Try again". By the way, your EAQ comment regarding common problems lists a defunct link to fmllibs16.zip and could instead show the above solution. Just a minor theory: Is there such a IPv4 setting for the MC-internal Java, too? Is forge trying to do network stuff? Full fml-client-latest.log: Windows 10 Before this problem, minecraft 1.12.2 already ran fine for a day with forge 14.23.2.2618, mods, shaders, etc.. The next day, Forge freezes. What the heck.
