Don't forget to surround any of the folder paths that contain Spaces with Quotes.
C:\"Program Files"\"Windows Defender"\MpCmdRun.exe –resetplatform
worked like a charm
Don't forget to run the CMD as administrator.
Added PowerBi Desktop to firewall app on Windows Defender.
Control Panel + Firewall Settings.
Solved.
