Creative Cloud keeps signing me out - minutes after logging in

Daniel, in addition to Kglad's suggestion, can you let us know if an organization manages any of the software or logins on the computer?  I am showing you are using an individual educational membership.  

You did a great job of choosing an e-mail address not managed by the educational organization, but if you have previously logged into a membership provided by them, then it could block you from utilizing an individual membership on the computer.  The steps listed in https://community.adobe.com/t5/download-install-discussions/unexpectedly-signed-out-of-adobe-application-or-membership/td-p/13244882 will fail in these circumstances.

reset the cc desktop app: make sure it's in the foreground, then press:

Win: Ctrl + Alt + R
Mac: Cmd + Opt + R

if that fails, try to repair
