Most of blocks are missed from my thunkable

I didn’t find some blocks can you tell me where I found lost blocks

Which blocks?

blocks like close application like many more with that my thunkable looks different from other so many features are not showing in thunkable

Is it possible that you are confusing X Thunkable with Classic Thunkable, which is a variant of App Inventor, with different components?
