I'm usually pretty good at this but I'm used to the old 1.12.2 ways of things. I recently made my own modpack and wanted to play with some friends on a modded Minecraft server I did every thing that I normally do to start it up but when I click "run.bat" it starts up then not even 2 minutes in it crashes out of nowhere. I've tried putting more RAM but no luck. when I take all the mods out though it works perfectly. If anyone can help me i would appreciate it thanks. i don't think its the actual mods either because on singleplayer they work fine.
