I can't authorize ADE with my Google account on my new PC.

I originally setup ADE on a system and made my last Google Play Store ebook purchase in 2016. Since then, I switched to Amazon. However, I've now installed ADE on my new system so that I can access my old Google ebook purchases, but also so I can switch from Amazon to Google for my future ebook purchases. I've tried many of the recommended fixes posted online and the Activation Server Error is the same regardless of what I try. This includes;

Trying ADE 2.0, 3.0, 4.0, and 4.5
Turning off Google 2 Factor Authentication
Changing my Google PW to an 8 character, letters and numbers only, PW

I deleted the Windows Adobe entries with Regedit between attempts and I even tried linking my Google account with my Adobe account in the Adobe account profile section, but nothing I tried worked, (after this failed I deleted the Google account link as well). In fact, nothing I tried even generated a different error message.

There is no prior authorization enabled on this computer, as this is a brand new installation, so there's no activation file on it to delete, or reset. Also looking in my Adobe account I see that there are no active authorizations, (although I don't know if that list includes ADE authorizations or only paid product authorizations). I also made sure that I deleted the "Third-party apps & services" link for my Adobe account, in my Google account profile, to fully clear everything on both sides.

If anyone has some suggestions for things I haven't tried yet, please feel free to respond. I'm really surprised that this has turned out to be such an unworkable situation. I'm literally locked out of all of my Google Play book purchases until this gets resolved.

TIA..

P.S. I am able to successfully authorize ADE with my Adobe username/password. However, I'm using the Google Play Store for book purchases and I assume that I need to authorize that account from ADE. (Please correct me if this is wrong)

So after successfully authorizing ADE for my Adobe account, I then deleted the authorization, (Ctrl-Shift-D) and attempted to authorize to my Google account, and it failed with the exact same error message as previously.
