I just installed 2.4.4 and after the install wizard I was presented with a blank page as the first look of the site I created. As it turns out, there;s some king of glitch in the THeme I was set to (don't remember which one) that resulted in my seeing nothing but whitespace. I appended my address with /admin.php (so the address is www.mywebsite.bla/admin.php) and was able to log in because the back end has a differenttheme on it. I was then able to get to preferences and change blocks and themes and fixed the issue.
Good Luck.
