Can't add email account to Thunderbird, loops on verification

Set up thunderbird on windows 10 with 1 email account. Everything was working, until it wasn't. Reinstalled thunderbird but when I go to add my mail account, I enter the info and on the gmail pop up, I enter my email, hit "next" and it asks me to enter my email address again. I have tried to configure manually with no success. I have confirmed my javascript is enabled in the config editor, I have added Thunderbird as an exclusion on both Windows Firewall and Windows Security, I have turned on third party access under settings for the gmail account, and I still cannot add the email account to Thunderbird. I don't know how to add my email account, this is very frustrating. Any help would be greatly appreciated.
