Constant sign-in loop in Creative Cloud and Photoshop

Question

Hi there,

I'm on Mac Catalina 10.15.5 and about 19 hours ago I received a popup from Creative Cloud while using Photoshop telling me to confirm my phone number in case I wanted to enable two-factor authentication. I did so, and ever since I have been stuck in a sign-in loop on both Photoshop and Creative Cloud. Before this, I'd only had photoshop for roughly three days and it worked fine for those three days. Each time I open either programme now though, I get prompted to sign in (my email address is already filled in and I cannot change it) and the only thing I get to do is push the sign-in button or close the popup, which closes Photoshop as well (or in the case of Creative Cloud it's just creative cloud that closes). If I press the sign-in button in Creative Cloud, I get a loading screen for a very long time and then I get told that I was logged out and need to sign in again. If I press the sign-in button in Photoshop, the popup closes for a second and reopens immediately.

Yesterday, after following multiple online solutions and completely reinstalling both applications I contacted Adobe support and over the course of four hours and three tech support people, a solution could not be found. Things that either the tech support people who helped me or I have done so far:

Follow these steps: https://helpx.adobe.com/creative-cloud/kb/creative-cloud-app-doesnt-open.html
- And these https://helpx.adobe.com/manage-account/kb/troubleshoot-creative-cloud-sign-out-sign-in.html
Uninstall all adobe-related apps and delete all adobe-related files that I could find and completely wiping everything again with Adobe's CC Cleaner.
- I also followed these steps and there is still a hosts file that can't be removed https://community.adobe.com/t5/download-install/can-t-uninstall-applications-manager-fix-host-file/td-p/7630762?page=2
Completely reinstall both Photoshop and Creative Cloud, multiple times
Turn off my firewall
Disable my VPN
Opened Creative Cloud again on a mobile hotspot, had a tech support person remove all keychains, had him log into Creative Cloud with his own work account (which did get access) and sync all files.
Removed all key chains and all adobe-related processes on my computer.
Delete and/or rename all OOBE, Cache, and Store folders

I've tried just about anything tech support, the internet, and I could think of but I'm just stuck now. After all these steps there has been no improvement whatsoever. Does anyone know how to fix this?

So after I posted this thread, I started fiddling with it again to try and fix it. One thing that occurred to me while reinstalling the applications again was that when it started, I was prompted to verify an email address and enable two-factor authentication, but during the fixing process, that kind of suddenly stopped out of nowhere, or it at least did it very selectively since I only have 7 of those text messages from adobe whereas I had to log in way more often than that. So, I looked at my account's security settings, and lo and behold, two-factor authentication was suddenly turned off. When I turned it on again and started photoshop again, I could log in with my email address and got a text message, filled in the code, and it's fixed! I don't know how long it will last but for now, it is fixed.

If anyone reading this has the same trigger for this issue with Creative Cloud prompting you to verify a second email address and use your phone number for two-factor authentication, please check in your adobe account's security settings if you have two-factor authentication turned off, you might need to turn it back on to fix it. From my four-hour-long experience with tech support, I can tell this is not really their first solution, but it worked for me and it is honestly the easiest solution out there out of the ones that I've tried.
