QuantumATK Builder crashes

[MarkusJech]

Hi all,

unfortunately, I encounter an issue with the builder. Up to now everything worked fine, however, starting from today when I try to open the Builder, QuantumATK starts to hang and doesn't react anymore. Below you can see the error message I get. This doesn't happen when opening other tools, e.g. scripter and so on. I would really appreciate some help here.

Best, Markus

It looks something broken.
Can you remove files under the user/.vnl/builder/? Before deleting them, it will be better to backup the files.
If it doesn't help, I recommend to reinstall the QuantumATK.

Thanks for the reply. I already did that, however, it didn't fix the problem. Nevertheless, it worked again fine the next day :-), so I assume it was an issue with some update on my machine?!

Best, Markus
