I've had trouble with this bug when using the better end / better nether mod. When entering one of these modded dimensions, my game would load for very long and then crash. In addition, within the first 10 minutes of being online in a world, my game will freeze and update frames very slowly making the game unplayable. But I've found a solution. Going into the minecraft launcher and finding your current installation under the installations tab and clicking on the dots and then edit. From there, hit more options and find the JVM arguments. The beginning will say Xmx or something similar. After those letters you may see 2G or any number before a G. This is how much RAM is dedicated to minecraft. The more you allocate, the more resources minecraft has. When playing modded its recommended to set the number before the G to atleast 4. When you play with 100 or 200 mods you may want to set it to the 6-8 range. Once youve edited this number, hit save and open minecraft.
