Can not display sign in box inside every cc 2019 app
Dear Adobe Team,
Please help me, my laptop can not displaying sign in box inside the program, it keeps on blank. so even after I close the sign in box, it is also closing the program as well. although I have been signed in in Adobe Creative Cloud. how can I sign in?
I am using Dell Inspiron 7460, and Win 10. I dont have this issues in adobe cc 2018.

I did turn off the anti virus and firewall, but it nothing's changed.
because of this problem, Ive downgrade the version to cc 2018.

Thank you in advance.
