Caused by: org.elasticsearch.gateway.CorruptStateException: Format version is not supported. Upgrading to [8.4.3] is only supported from version [7.17.0].

This is not supported, you need to upgrade first to the last patch version of 7.17.X and check the upgrade assistant if you need to change anything.

This is the first thing you see in the documentation page, please check the documentation.
