Hmm. So it's not a problem with mods.

Sorry if that didn't make sense, it's a bit late for me. I'll try and do a bit of a better job.

Currently, your JVM flags (the part where you add more RAM in your launcher settings) look like this: XX:HeapDumpPath=MojangTricksIntelDriversForPerformance_javaw.exe_minecraft.exe.heapdump -Xmx1G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=16MAABB If you need those flags to make Minecraft run the best it can, then go ahead. However, those look overly complicated to me, and it seems possible that one of those is causing MC to not respond (don't quote me on that).

I would recommend to try and change that to just -Xmx1G and see if that fixes or changes the problem?

(for reference, the JVM flags I am currently using that I probably got from some MinecraftForums post are -Xmx2G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn256M, and it seems to work pretty well.)

Hope that cleared up what I was trying to say
