Power BI Report Server January 2025 bug

Hi,Kostya_Rico and mfarhanjamil .Thank you for your feedback.
Hello,TomOm .I am glad to help you.
You can try to grant permissions to users.

reporting services - The permissions granted to user are insufficient for performing this operation (rsAccessDenied) - Stack Overflow

I have noticed that the issues are all occurring after Power BI Report Server has been updated to the January 2025 version. So I can not rule out this as an update issue at this time.
I've checked the relevant report server information, but I'm not aware of any similar known issues at this time
I think you can create a Microsoft Support Ticket to get more help.
This will allow you to get more information about your environment configuration as well as error messages to help quickly determine the cause of the problem.
Thank you for your support of Power BI.
