Re: Infinite loading
Ah I see, seems like you are one of the few unlucky people that is encountering this issue.
I'm not really well versed with this variant of the issue, so hopefully someone else knows a fix for this.
Personally I'd recommend checking the settings in your Antivirus and Firewall to allow Apex to pass through without any problems.
It might also be worth a try to run Apex with administrator privileges.
