That is not common but there have been some cases show up.

One thing to check is whether you are installing any software beyond MATLAB itself? For example are you adding a path to some MATLAB tools provided by your professor?

It sounds like there are error messages showing up? It would help a lot if we could see those.

Run

bench()

Does it run a number of tests and produce a bar chart of performances? See MATLAB benchmark

You absolutely must rename your class.m to something else. class() is an important function in MATLAB implementation, and your class.m is interfering with it.
