The initialization of $wgExtensionDirectory changed in 1.38:

I don't think that should be a problem, though, unless you're using
$wgExtensionDirectory to define another path in LocalSettings.php. What
happens
No, not setting $wgExtensionDirectory. Extensions all are loaded with
pattern like wfLoadExtension( 'Cite' ); .
I updated this installalation a few days ago from 1.36.0 to 1.36.2
without having any issues. The bug suddenly appears when updating from
1.36.2 to 1.38.0.
