Sure thing. Attached is the text file - it's as I've reported before. My device, plus an additional offline emulator with no additional identifying information.
I also attach a screenshot of the failstate - note in the background my sequential adb devices -l commands; initially no second emulator, then I hit go on the installation, it succeeds in the play services then boom there's this second offline emulator and it's error city in toolbox.
Already did the back of my computer text, updated my posts above with my report from that (error: failed to connect to download server). Additionally I've since powered off all smart devices in the home, no behaviour change. So, confirmed local I think.
I'm no expert but it seems to me that the emulator(s) being detected is(are) being generated by Toolbox itself. Have you tried manually installing Google Services with the instructions from @Falcon342 in posts #5310 and #5312 ?
