macOS Catalina installation stalled after clicking on "Install"

I have a 2013 iMac running OS 10.9.5 and I downloaded macOS Catalina to upgrade. When shown the choice of disk to install it on, I chose Install. It is 9 hours later and the macOS Catalina box is still there. There is only a yellow dot (no red or green dot) in the dialog box, and clicking on Install or Back has no effect. Activity Monitor shows no CPU or disk activity. Since I can't close the dialog box, how should I proceed?

Thanks.

In addition to these same symptoms, I am also getting messages that state the following:

OS X wants to use the 'Local Items' keychain
talagent wants to use the 'Local Items' keychain
messagesAgent wants to use the 'Local Items' keychain
CalendarAgent wants to use the 'Local Items' keychain
AddressBookSourceSync wants to sue the 'login' keychain
AddressBookSourceSync wants to sue the 'Local Items'' keychain

And when I try to open safari it is giving error message 1712!

lasltly, I know cannot see any versions of operating software available on the App Store other than Catalina!

Please help!
