Debugger freeze

Hello I stumble into the following:

While using the debugger, after stopping at the desired breakpoint and executing step over afterwards the debugger freezes sometimes. It is really irritating because it happens quite frequently but not always. If I dont put any breakpoints the code runs fine. The program is a simple pytorch lightning routine. While at the breakpoint sometimes it will show me the variables but sometimes it puts out "Collecting data"
