IS THERE ANY PROBLEM IF I TAKE SPECIALIZED COURSE OF CSE WHILE DOING MY MTECH DEGREE???

Akash No,actually.but it depend on how focused you are..generally in CS field no matter what you studied,but it is necessary to have good skills and fast learning capacity in IT corporates...but when moving to core jobs related to IT its little different,you need to focus on some concepts like oops,pointers,something like that...
When you ask about evolving technologies it is good for you to learn things like IOT,Data science,Machine learning etc .Hope you got it...Thanks for hitting like anyway...
