Hi @Stepper, Ludwig ,
Welcome to Microsoft Q&A!
For SSRS(Microsoft Reporting Services Projects), you can install it from Extensions > Manage Extensions or from the Marketplace.
For SSDT, you need to install it through Visual Studio Installer > Individual components > SQL Server Data Tools.
After installing SSDT and SSRS, please re-launch your VS2022 and create the report server project again.
For more details, please refer to: SSDT for Visual Studio 2022.
Sincerely,
Anna
