Hi Abhijit,
Welcome to Q&A Forum, this is a great place to get support, answers and tips.
Thank you for posting your query, I'll be more than glad to help you out.
1.) The SQL Server 2019 will - as usual - also an extended support lifetime until Jan,. 2030
https://learn.microsoft.com/en-us/lifecycle/products/sql-server-2019
2.) technically I would think: "Yes, Devops Server 2022 will run (and support) SQL Server 2022" but the official statement is still missing.
Maybe one of the Microsoft employed forum supporters might answer here too. (after clarification internally)
I hope my answer is helpful to you,
Your
Bjoern Peters
