wp-admin login issue with redirect and reauth=1

when i try to access my wp admin dashboard it redirect me to login.php page and it shows blank white screen.
the redirect url is
https://www.ahmedglassworks.com/wp-login.php?redirect_to=https%3A%2F%2Fwww.ahmedglassworks.com%2Fwp-admin%2F&reauth=1

i tried deleting the plugins and recreated the .htaccess file and forced site to shift to default theme and i cleared the cookies and also tried in incognito mood but nothing worked.
although wordpress is logged on my phone previously and it is still working on it but i can’t login or open my dashboard when i try to login on my laptop and any other tab in my phone and it do not work on client device.
