I was just making custom mobs with the HandItems tag. I spawned in the mob and my game froze shortly after. (It's not because I did the parsing wrong, it spawned, and then there was a few second timelapse) I tried the F3 + C for 10 seconds method, but it was lagging that hardcore, that it didn't register. From that point whenever I spawn a mob with that tag on this world and ON ANY OTHER ONE THAT I HAVE it freezes my game EVERY TIME, causing my computer to crash or shut down Minecraft with the Task Manager.
