PBIX bug -- Delete/Change table relationships

Hello everyone,

I've experienced lately an issue when I try to delete or change a relationship attribute (e.g. cardinality). It keeps on showing the "working" revolving icon without finishing. 

Version: 2.118.621.0 64-bit (June 2023)

I presume it might be related to the latest update because I haven't faced it before with the same file.

Cheers,

Tarek
