android - Androidstudio 4.1.2 Native debugging not getting connected and app crashes

Question

I'm hitting this issue in Androidstudio 4.1.1 and 4.1.2 Whenever I try to debug the app in dual mode, the app crashes while androidstudio tries to start native debug session and then it fails to connect to the debugger(obviously!). Here's the details from the idea.log:
