I have linked a collection of a blend file in another blend file (Main Comp). I have activated the "Linked Library Add-on" in Preferences. I can switch from the Main Comp to the linked blend file via the button "Edit Library: Collection". This works without any problems. But strangely I can't get back from there. In the add-on the option "Return to Original File" is not offered. Did I miss something? Thanks for your help!

    $\begingroup$ This looks like something bugged out. Could you go to Window > toggle System Console and copy paste errors in your question (if any) ? $\endgroup$

Judging by the error that's being repetitively printed out in the system console :

icon = "OUTLINER_DATA_" + context.active_object.type.replace("LIGHT_PROBE", "LIGHTPROBE")
AttributeError: 'NoneType' object has no attribute 'type'

The add-on functionality assumes that you have an active object in the code, apparently in order to draw something in the panel interface. Normally the developper would safeguard the code so this doesn't happen, but this edge case hasn't been taken into consideration.

You would need to select an object in the interface so context.active_object doesn't return a non existant object and the interface draws correctly.
