Press Windows + R , type%appdata% find the CrowdControl folder there, right-click, compress it. And send it to me in a DM on Discord, it contains sensitive information.
Solved this in a call.
Windows Defender was blocking the DLLs for Crowd Control from loading, so they were unable to connect to the server.
Other issue was fixed in a client update that no longer exists in CC versions 6.2.5.
