Can confirm, had the same issue with 12.2.0, thought it was just powershell, but once I rebooted the server, client and service failed to start.
Took a snapshot of the vm, ran the 12.1.4 installer, and i'm back up.
This assembly is protected by an unregistered version of Eziriz's ".NET Reactor"! This assembly won't further work.
It appears they need to update their license of the code obfuscator! How exciting on a holiday Monday (in the US at least)
... and i tried to post this message and now i'm getting a yellow screen of death. Everything ok over there?? 😰
