Could you please confirm that you are using the cloud.uipath.com Orchestrator with the Community Stable EXE installer 21.4.4?
If so, this message is purely due to the latest Community version being higher than your current version. This message does not block any functionality though, so no worries.
Also, it should probably be adapted based on the Studio channel that you are using (Stable vs Preview) and our product team will look into improving it.
