Hello, my system will no longer function after this update. I am on Gnome and it says something went wrong. After downgrading gnome-shell from 3.38.3 to 3.38.1 I no longer had this issue. 3.38.2 was also broken. I have no idea what is wrong, but can pull up the journal message for it
Welcome to the forum! 
The most common issue is a misbehaving extension. Try disabling all extensions, update all packages including gnome-shell and reboot.
the issue was actually having a gjs-git version installed along with a few other development packages
