Is there any study that shows that typing in Python improves code quality and reduce runtime issues?

No, static typing is usually used AOT (most frequently at compile time), not usually at runtime (types may or may not exist at runtime; they don't in Haskell, for instance.)
Python type checking is also AOT, but (unlike where it is inextricably tied to compilation because types are not only checked but used for code generation) it is optional to actually do that step.
Python type annotations exist and are sometimes used at runtime, but not usually at that point for type checking in the usual sense.

In fact, Haskell then allows you to add back in runtime types using Typeable!

Educate yourself before making such claims.
In my case they just add noise when reading code and make it more difficult to review
