Busy, Please wait (while trying to d/l macOS)

I have tried both ver 2 as well as a beta ver 3 to download MacOS images since I cannot do it through the App Store as my MacBook Pro is pretty old running High Sierra. All works as expected after creating SSL and selecting the "Download macOS from tools. That catalog appears with versions of High Sierra, Mojave and Catalina. I select one of them - select the folder I would like the image to go into and then next screen just sows Busy, Please Wait… X

Open up the log by pressing command-L and it should print the status messages as it is downloaded.
