I am getting following error when running emulator, also debugging is not working, it says waiting for debugger to attach. I am wondering if the following has anything to do with getting stuck at "waiting for debugger to attach".
Emulator: E0516 21:01:34.057349753 3279 socket_utils_common_posix.cc:201] check for SO_REUSEPORT: {"created":"@1589644894.057229268","description":"SO_REUSEPORT unavailable on compiling system","file":"/mnt/tmpfs/src/android/emu-master-dev/external/grpc/src/core/lib/iomgr/socket_utils_common_posix.cc","file_line":169}
My android studio version is below.
Android Studio 3.6.3 Build #AI-192.7142.36.36.6392135, built on April 14, 2020 Runtime version: 1.8.0_212-release-1586-b4-5784211 amd64 VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o Linux 5.4.0-29-generic GC: ParNew, ConcurrentMarkSweep Memory: 1246M Cores: 4 Registry: ide.new.welcome.screen.force=true Non-Bundled Plugins:

I had that problem.
I was making a wrong diagnostic.
Running the emulator from Android/Sdk/emulator/emulator with a command such as:
./emulator @Pixel_3_API_28 -netdelay none -netspeed full -debug all also gave me this error, but it is non-blocking.
The problem disappeared when I:
switched to proprietary driver (nvidia) in Ubuntu in the Software Updater > Settings > Additional Driver
Restarting
Recreating my virtual device.

I think this is maybe related to fix in Emulator 30.0.18 (https://androidstudio.googleblog.com/2020/06/emulator-30018-canary.html). Try to update your emulator with different channel
sdkmanager --channel=3 "emulator"
For "waiting for debugger to attach" try to also delete all breakpoints if it helps.
ps: I am a bit duplicating my answer with https://stackoverflow.com/a/62793395/13891284 but can't really mark as duplicate

I found a way to lauch emulator after understanding it was a GPU issue...
sudo ubuntu-drivers autoinstall
Changed problem to another :
Blockquote Error while Running Android Application - Could not initialize OpenglES emulation, use '-gpu off' to disable it
So according to this issue and this answer I changed the emulated device for one that allowed me to change 'Software-GLE 2.0' for Graphics，not select 'Automatic' or 'Hardware-GLE 2.0' (emulate graphics in software) (not all of them allow to change it) I used Galaxy Nexus API 30 - R and emulation worked, even I still have this SO_REUSEPORT error ! Hope it can help someone ...

The emulator was showing a android setup notification. Once I clicked on that and setup the phone, the emulator started working for me.

Switching the camera options from Emulated to None fixed it for me.
