I'm pretty sure that a PHP notice will not result in a WSOD.
So try to look at some other logs (apache, sql, maybe try stepping through a page with xdebug) and see if you can find more errors.

And I'm pretty sure this doesn't happen on a clean 8.4.4 install so it has to be something specific in your install.
So maybe try switching of modules and see if you can pinpoint which one is causing problems.

Hi @mudassar774, just faced the same issue while installing modules. What was the issue for you?

UPDATE: there was some DB updates missing for me. Update.php solved the problem.
