Debugger gets stuck

[spin711]

Issue Type: Bug

While debugging a python script, the I cannot continue stepping through the code since MSC debugger is not responding anymore. At least for me, it seems that it gets stuck after 15 successful times of stepping. This is repeatable.
Also the debug console is impacted, meaning I do not get a requested content of a variable once the above happens.
Please fix asap, since one cannot work with this version anymore properly.

Are you able to update to the current release (1.44.2) and retest?

[spin711]

Yes, I updated to version 1.44.2, but the same issue. The only thing I observe is, that the number of steps I can perform is not as constant as I thought within the same script. Although it seams repeatable starting at the same line it changes when the starting position and thus the lines of code are different.

[spin711]

There seems to be also a dependency with the number and the type of variables in the watch.
