Dax query restricts saving the project

Cheers,

thanks for your quick response.

Unfortunately your tips are not the solution.

The characters of my file path do not exeed 260 characters.

There are no special characters in my file path.

A simple restart does not help either.

I set up the exact same database on two several PCs and on both clients I experienced the same problem.

I want to stress again that the second I execute code in Dax Query Area, PowerBI will not let me save the project.

When not "touching" the Query Area and just working with diagrams there is no problem at all 🤔
