Appium on mas os, Could Not Launch Appium Inspector

Hello. After launch Appium, i click Appium Inspector then i have error alert:

Could Not Launch Appium Inspector
Could not start a new session

Be sure the Appium server is running with an application opened by using the “App Path” parameter in (along with package and activity for Android) or by connecting with selenium client and supplying this in the desired capabilities object.

error on log:
