Current Behavior

I have a setup where the android emulator is running on my windows machine but my project is in WSL2 on the same machine. I have setup adb so connected devices and emulators are shown when I run adb devices inside WLS2.
Unfortunately when I run npx cap run android I get the following output:

Expected Behavior

I expected capacitor to connect to my emulator running on windows.

Other Technical Details

I've done some digging and found that native-run only looks for hardware devices using adb and if none found tries to open an emulator (see ionic-team/native-run#213). In my case it tries to start an emulator on my WLS2 which is not setup.

The issue is on native-run, you already reported it there
ionic-team/native-run#213
