"65 or more items" means 65 or more items in the same stack.
My pack works properly with the stack size of 64, so it looks like stack sizes of 65 is not permitted and freeze the world.
As stated in MC-206962, Stacks of larger than maximum stack sizes are not supported.
Please explain what you mean by "65 or more items"?
It appears that you are trying to exceed the allowed stacking limits built into the game.
Does your pack work if you set the limit to 64?
We cannot generally help you "debug" your resource pack, so you might also want to visit Community Support for help.
