The options when you boot are the kernel versions not the Fedora version. You’re not booting into Fedora 38, you’re booting Fedora 39 with a 38 kernel.
There’s nothing wrong with using a Fedora 38 kernel on 39 if it works. There’s probably a kernel bug affecting your computer in the current 39 kernel that’s making it not work
The easiest solution will be to wait for a new kernel and hope it fixes this bug
