Plugin from Marketplace doesn't install

Hi, I’m trying to work with the obligatory ShooterGame template on Mac, but it requires Procedural Rooms plugin to be installed (also, why can’t UE just install all required plugins at once??). When I press “Install to engine” in EGL and choose the engine version, that’s it. On confirming the engine version, the dialog closes and nothing else ever happens. No error message, nothing. I’m unable to use the Shooter game template. Rebooting and reinstalling EGL didn’t fix. Other plugins install fine.

On a related note, sometimes I can’t click links inside the marketplace. Like I open the “Free” heading but clicking “Free for the month” does nothing. Other apps work fine.

Please help.

MacOS Catalina 10.15.5, UE4.25.1
