I had been dealing with this bug as I stated in the comment section for a while in Android Studio Canary. But it seems like this is a general problem that newer Android Studio versions have. So, these steps would work for most people.
Uninstall Android Studio including the user settings. (Don't delete the folder. Uninstall properly.)
Download and install Android Studio 4.X or Canary as you prefer. And, do not accept old user settings if the Android Studio ask you to choose it. In my case, it did not ask but it worked like a charm.
Open the project
And voila.

Same, Took a while as there were a lot of processes running. Eventually my plugged in devices came up just as I was about to "File... Invalidate Caches and Restart"
Did it eventually come back up for you?

This is an issue with the latest Android Studio version. The only way to overcome it right now is to open the Android Studio terminal and run the start-server command manually:
/Users/[YOUR_USERNAME]/Library/Android/sdk/platform-tools/adb start-server

For me, having environment path of adb set caused stuck at "Loading Devices". I removed the environment path and restarted Android Studio, my device could connect again
It still not work with Memuplay emulator. I have to launch another emulator called LDPlayer and reboot Memuplay while LDPlayer still running, it will now connect to adb
