From the screenshot of the errors it looks like the name is, “emulator-5554”.
Also, the error is no longer, “Environment not available”, but is now, “Unable to install apk”. It looks like you are making progress, frustrating as it is.
Edited to add: If it were me, I would bring up the emulator manually and try installing the apk with the adb commands you see in the error log to see if I could pin down exactly what’s failing.
