Since end of 2022, there is also a SQL Server Integration Services Project template available for Visual Studio 2022 which you can install from the Visual Studio Marketplace. You can install it from the direct download link here or you can search for it in the Visual Studio 2022 extension manager and install it from there.
My installation of SQL Server Management Studio 18.0 last week always got stuck on the initial "Loading packages. Please wait..." screen. The solution which worked for me was deleting the registry key underneath "HKLM\SOFTWARE\WOW6432Node\Microsoft\Microsoft SQL Server Management Studio" as outlined in Installing SSMS 18 won't go past loading packages phase.
