Hi @Voltes Devpro ,
Welcome to Microsoft Q&A!
Could you tell me how you bought the Visual Studio 2022 license?
You cannot use the product key of VS2022 to VS2019. Please find the key for VS2019 on your Visual Studio Product Keys page.
If it is not available, you may purchase a standalone license. If so, it is not entitled to the earlier versions.
Sincerely,
Anna
