Unable to access library editor

Hi,

When I try to access the libraries panel of my project, DSS loads indefinitely (see screenshot) or sometimes prompt a network connection error message

All the other tabs, notebooks execution etc... seem to be working well. I've been to DATA_DIR/config/projects/TF2/lib/python and there is nothing suspicious there.

I can't simply restart DSS - I assume this will stop other computations running in notebooks from various users and this might cause some trouble. Is there a way to solve my problem without restarting the whole DSS?

Thanks in advance.
