This is an issue I had using Appium from a Mac on Android.
Appium isn’t able to detect activities from my app. It was detecting these fine with another version of this app, and I’ve confirmed with the developer that I’m using the correct appname and activity name.
I opened my app in Appiumgui to check the activityname, and no activitynames are showing up. In the older version it does.
Here is my log when I tried to run with Appium Inspector (with the name of the app replaced).

It turns out we had multiple versions of the app with different app package names, and there was miscommunication between the developer and I about this. Once I used the correct name for the version I needed, everything went smoothly.
