Version 8 installer won't move past moving data in an empty standalone vault

I was running the 1Password 8 beta on another machine so I have some familiarity with it. On my primary machine, I decided to proceed with the upgrade with the first release. When I launch the installer, it determines I have a local vault and prompts me to move it. I tell it to go ahead and the dialog says "Waiting for data to be moved. Don't quit this app." Nothing happens.

I of course know my standalone vault exists but it is empty. I'm long time 1Password user and I have a Family subscription and use 1Password at work, so a number of cloud vaults as well. I continued to use a standalone (local/primary) vault in 7.x because I wanted a less complex password to open 1Password. (I already have other factors of authentication and security, including a very long password on my 1Password cloud account.)

I thought, "ok, maybe the installers is confused by an empty standalone vault". Not a great start for a first release that has been in beta for quite a while but a simple fix. I launched v7 and added a single dummy record to the standalone vault. Quit, re-tried installer. Same thing.

I'm quite obviously quitting the installer anyway, as it is painfully obvious it's not doing anything with a 0 record local vault for anything over 5 minutes. I know I could safely proceed to go with the "Install without moving data option" and move on with my life (if it works, which I assume it would) but then the scenario here could be lost for testing and feedback purposes.

AgileBits team, please let me know if there is any insight you can provide or information I can provide towards determining the issue here.

p.s. I also tried the posted 8.8.0-11 installer thinking maybe this has since been addressed but same result.

Thanks
