Error while excecuting the query, because the Cube or internal structures couldn´t have been process

Hello community,

I have the following error while opening a shared SSAS Power BI report with one specific user.

Error text: "Error while excecuting the query, because the Cube or internal structures couldn´t have been processed (or aren´t available)."

All other users in the organisation don´t have this error with opening the report.

The following things are given:

• The user have a activated Power BI pro License
• The SSAS Cube structure is delpoyed with no errors
• All other users can use this report with the Live connection to this cube with no errors
• All users are registrated on the same domain
• All gateway configurations in Power BI are set correct
