Hello,
I've been having problems with forge, haven't played in a while, so maybe I'm doing something wrong.
Minecraft vanilla 1.12.2 runs fine (with Java 32-bit and 64-bit)
Forge (1.12.2 2655) runs fine with Java 32-bit (but it crashes on low memory if I install mods, obviously), with 64-bit it stops after buiding terrain and stops responding. I've tried both the minecraft launcher and MultiMC, same behaviour. Java 32-bit version is 1.8.0_171 (the lastest one), Java 64-bit I've tried 1.8.0_171 and 1.8.0_25 (which minecraft installed in it's folder)
PS: I've tried with no mods installed
I can't get a crash report, since it loops and Windows closes Java. I get a "Process crashed with exitcode -805306369." in MultiMC. In 64 bit I'm trying Minimum memory of 1024 MB and max of 2048MB.
Minecraft logs stop at this:
[net.minecraft.server.MinecraftServer]: Preparing spawn area: 85%
[22:12:14] [Server thread/INFO] [net.minecraft.server.MinecraftServer]: Preparing spawn area: 99%
[22:12:15] [Server thread/INFO] [FML]: Unloading dimension -1
[22:12:15] [Server thread/INFO] [FML]: Unloading dimension 1
Process crashed with exitcode -805306369.
I have 8GB of RAM, Windows 10 and a GTX 1050 TI. Nvidia drivers are the lastest, Windows 10 is updated.
I usually don't post in forums, but I've been googling this for 2 days already.
EDIT: The problem was a security software called "Trusteer IBM Security Rapport", uninstalling it solved my problem
