Pydev Debugger not working with breakpoints, pydevbreakpoints

Pydev Debugger not working with breakpoints, pydevbreakpoints

I have a simple test module:

Print ("fish ")
Print ("sticks ")
It runs pretty fast as expected, wether I use Run as or Debugg as does not matter.

But as soon as I enter a Breakpoint the Debugger starts (pydev debugger: starting (pid: 2696) but does not reach the breakpoint nor finish the program (> 5 min ).
I suddenly had this problem in a bigger project and created this test module to see if the debugger works. I did not change any settings in the prefrences menu of eclipse. i'm using python 3.x with the anaconda interpreter.
I restarted the computer and updated eclipse and pydev.

Answer:
I found that deleting. metadata from the workspace solves the problem. But I have no clue what caused the issue.
