2021.01 Release Notes
Indeed, this is some weird bug with WavesLocalServer that we found earlier. I've already reported it to Waves.
If you run into it the workaround is to kill that task before installing or reboot the machine. I'm sure its not intended to be permanently running since a clean boot doesn't run it.
