Creative Cloud won't let me sign in, likely due to a deleted account

Recently I've been having an issue with the Adobe Creeative Cloud app where it repeatedly asks me to sign in after opening the app, as it says I've been signed out (See attached video). The problem could be due to a previous account that was used for the Creative Cloud on this computer, but it was a school account, and was deleted recently since I don't attend the school anymore. I've tried uninstalling every Adobe app from my computer and even wiping every Adobe file from my computer and reinstalling several times, but nothing has worked. The problem prevents me from downloading, updating, or using any apps, so any help to resolve it would be much appreciated.
