Unable to play any 1.12.2 modpack

[pebbletwig]

Good day,

I have been unable to play any 1.12.2 beyond the first time.  At first it had to do with CraftTweaker, as stated here, but after any solution I found not work I just got rid of CraftTweaker. Now, minecraft boots the first time after a fresh modpack install, but freezes at modidmapping any time after the first. I am currently trying to play the MC Eternal modpack, with only a couple qol extra mods, and it gets stuck with or without them so they are not the problem, and one suggestion said give more ram, so I did, but that did not help, it still gets stuck, with plenty of ram remaining. I have no idea what could be causing it to get stuck at modidmapping. Here is the latest log from when it got stuck and the log before that that did not get stuck, along with the debug logs from the same thing. Also, I use optifine but I have tried running it without optifine and it will still get stuck at modidmapping. Any help would be greatly appreciated, please and thank you. I have tried asking everywhere and have gotten nothing, this is the only other place I could think of.

Successful boot log

Successful boot debug

Edit: After digging through the logs I found that in the successful boot log that it says ModIDMapping took ~900 seconds, or ~15 minutes. This can’t be correct, as when I sat there and watched it boot it took only 8 minutes to fully load up. But in the unsuccessful boot log, it says ModIDMapping took 0 seconds and nothing else. I don’t know what this means.
