After config all settings. I can enter the logon page. But when I try to logon or register, it shows me below error. Is there anyother setting needs to be done?

An error occurred while attempting to add the account. Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Hi,
We tried the Sample solution , built the project using VS 2022 and deployed to SSRS 2019 but got the same issue as reported above by @Cavan001 . Is there a fix for the same, we are unable to connect to Database?

Note: While building the project, we changed the Target framework to 4.8 as it was not referring the SSRS 2019 Microsoft.ReportingServices.Interfaces properly and hence getting many build errors.
