That's not an error, it's just a warning made it look like an error. Manifest V2 extensions will keep working till January 2023. You don't need to do anything for now.

Its making the extension not to always function properly, so how to resolve and how to update to manifest version 3?

If the extension is not yours, then there is nothing you can do. The author of it must migrate it to manifest v3.

If the extension is created by you, then you could start following this guide: https://developer.chrome.com/docs/extensions/mv3/intro/mv3-migration/
