Then I can connect with Android Studio and then restart Chrome and reconnect. If Chrome is connected using chrome://inspect, then adb seems to disconnect. After trying many other posted solutions, I discovered that the issue was with Chrome also trying to connect its debugger to a web view. I have been fighting for a few days with adb not seeing my device. This particular comment in one of the above issues clued me onto a possible root cause:

Android debugger continually disconnects.

Android Studio Arctic Fox (Adb) - Connected Devices are being disconnected after some time.

I searched and read through remotely similar issues, including (but not limited to) these:

A great number of further possibilities, to no avail.

Reinstalled build tools/platform tools, and ADB.

Revoking/reaccepting USB debugging authorization.

Invalidating caches and restarting Android Studio.

Plugging the USB cables into different USB ports on my computer.

With various versions of the Android Studio IDE (as mentioned above).

With different handsets (both varying makes and models).

I've tried a fair few things in an attempt to determine a root cause. Everything appears fine initially and I may even have enough time to deploy my project to the handset, before the device disappears from Android Studio (as if I'd physically disconnected the USB cable from my computer or from the handset itself). The issue occurs soon after opening Android Studio ( Bumblebee+) with one of my physical devices connected.

I've reproduced the issue on Android Studio Bumblebee (Stable), Chipmunk (Beta), and Dolphin (Canary), but Android Studio Arctic Fox (superseded Stable) continues to work just fine.

I can confirm that the issue was introduced from Android Studio Bumblebee onwards (occurring in Beta and Canary builds also).

Unfortunately however, since updating, physical devices/handsets don't remain connected to Android Studio for the purpose of debugging.

I jumped on this stable release, updating from Android Studio Arctic Fox (2020.3.1 Patch 4). Android Studio Bumblebee (2021.1.1) was released stably on 25 January 2022 bundled with a new Device Manager (accompanying new support for Android 11+ device debugging over WIFI).
