Mac Client has memory leak trying to register the registration code?

I have a windows and ps4 version registered on my account. Just bought Mac version. When I log in, enter the registration code and click Next, the app just hangs sucking up memory until it hits 250 GB and Mac OS pops up the dialog saying I'm running out of application memory and to force quit the application.

I have 32 GB of physical ram. It is pretty obvious there is a memory leak when the OS is telling me it is using 250 GB and I can watch the number just keep increasing...

macOS Mojave 10.14.5

I don't recall the client ever asking for a registration code. IIRC you register it on the mogstation website. Once it's connected to your account you should only need your user ID and Password (and one-time password if you do that). Are you using the current 64 bit installer? Maybe delete whatever was installed and the installer and download a fresh one.
