Yes.. your right!
I somehow forgot to add it.
And I fixed it and the game doesn't crashed anymore.

I am sorry to report it because it is my
Mistake and not a bug!

But thank you so much for looking into it.
Now I can enjoy my blocks 🙂

A little more info:-
i tried it on my pc..
i.e., Windows 10 edition

and the same thing happened!
the game crashed with this addon.

so i see the issue is with the addon! but dont know why?

Dear mojang,
There are few other things that should be in a target block

1. A comparator should need to get signal strength of the Redstone dust beside of the target block and check nbt blocks and out put a Redstone signal...

2. Target block should allow Redstone dust through it even tho it will be a solid block(this could be a feature if you devs will)

And thanks for reading this...
