Bug with my scripts since the update

Since the last Illustrator update (27.5), my script no longer works (tested on several computers).
Do you know where this can come from?

This is the message : 

To create a work plane, select a non-rotated rectangle that is not a clipping mask.

For the record, my script worked perfectly before, I didn't change anything, and I don't have: any unrotated rectangle, any clipping mask.

Thank you very much for your help !
