I purchased and downloaded turbotax 2023 from the internet, but intuit is denying access to my account

Well, after 2 hours talking with someone from Turbotax Customer Service, who was very kind and patient, I am no closer to being able to activate my desktop version of turbotax premier 2023. 

After clearing the cache on my Chrome browser, I can no longer access my intuit account on that browser, although it is accessible through Firefox and Edge. After clearing cache and allowing cookies and popups, Chrome is now asking for my password, and then telling me: "We are unable to sign you in. There may be an issue with your system configuration. Make sure your browser has Javascript and cookies enabled. If the problem persists you can clear your cache and cookies and then restart your computer, or try using a different browser. Try again. For more help, please contact customer support and reference code 25625." I have tried changing settings in Chrome and clearing the cache again, but can't seem to get it to work. Moreover, the Desktop software is still giving the same "Access is denied" message when I give it my email, and it never allows me to enter a password.

I've tried re-downloading the software with and without a VPN from Thailand, with no change in software behavior. I'm guessing the problem is somewhere in my Windows settings related to cookies and popups, but can't seem to find anything. Any suggestions are very welcome. I've been using turbotax from Thailand for over ten years now, mostly without a VPN, so I don't think that is the problem. I have multiple (more than 5) older versions installed on my desktop, but don't think that is a problem either.

I would greatly appreciate any suggestions that would allow me to install turbotax.

I've tried setting Edge and firefox as default browsers, but that doesn't seem to change anything. Any ideas on how to change the settings that are used by the desktop software when logging into intuit?
