Segment Editor not working

Hi all
I hope everyone is doing great.
I have a question. I have an issue with the “segment editor”. The segment editor module is empty, and there is nothing to add. Does anyone know what it might be?
Best,
Arash

Have a look in the log window for more information.

If you don’t figure it out, post the log here (see Help → Report and issue) and describe if you installed any extensions or did any other modifications.
