Hey, sorry about the trouble here.
Thanks for the screenshots. Your property is a Google Analytics 4 property. If you would like to connect to MonsterInsights, you’ll need to create a Universal Analytics property.
When creating a new property, you’ll need to enable an advanced option called “Create a Universal Property only”. Here’s our step by step guide on how to do this: https://www.monsterinsights.com/how-to-add-a-property-in-google-analytics/
For more information about why we don’t support Google Analytics 4 properties yet, please see this response https://www.ads-software.com/support/topic/google-analytics-4-tags/#post-13583216
