Unable to run windows desktop app on android studio using flutter

Question

I'm new to flutter dev and android studio, so basically whenever i run my app on windows(desktop), my app opens for 20sec on windows but then gets closed automatically.

It shows :

"LOST CONNECTION TO DEVICE" ,

I don't know what is the problem !? I didn't even have the app.so file present in any folder, I had to ask a friend to mail me this file, and even after pasting the file in the

build->windows->runner->debug folder, it's showing the same error.

flutter doctor -v result is :
