Unable to start device

I am trying to run my Android app on a physical device. I’m using a Samsung S7 and getting an error when trying to run the app: Unable to start application on this device: An unknown server-side error occurred while processing the command. Original error: Error getting device API level. Original error: Error executing adbExec.

Sometimes when I run, it will restart my app on the device but, I’m not able to do any recording. When I restart adb.exe, it hangs on:

I’ve restarted all my components and devices.

Please advise.
