Bug description

Android Studio Debug Mode is not working. The app package does not show up. It was working in version 12.8.

adb shows the process is present.
adb shell ps | grep artium

Steps to reproduce

1. Install any debuggable apk from Android Studio(Version: Panda 4 Patch 1). It will show Waiting for debugger to attach

2. Android Studio will show after few seconds, that process id was not found

Relevant log (logcat/build log)

adb shell ps | grep artium

Output:

u0_a406       5703   951   17060052 284856                     0 S com.artiumacademy.mobile.app.qa

Screenshots or videos

adb checking is process is present or not:

Solution

I think the issue is something related to JDWP(Java Debug Wire Protocol). When the app shows Waiting for debugger, you can check the PID using command:
adb jdwp

But in our case, it gets stuck until it is stopped manually.

Additional context

This is not a JDK or an Android Studio issues, because I have tried the same with my Samsung S23 on stock OS and it works. Also I updated yesterday which is 5th May. Before that it was working perfectly on CrDroid 12.8.

I have also tried clean flashing the ROM it does not work.
