It is not solved, yet,
What you did is not different from asking people to download any different version that works, like the 37 beta, 38 beta or rawhide.
If the options from the official download page, or from fedora media writer are not working as intended, the problem is still there.
Nothing solves “itself”, people worked on it
2142968 – pyanaconda.modules.common.errors.installation.BootloaderInstallationError: Failed to set new efi boot target. This is most likely a kernel or firmware bug.
2144186 – Fedora 37 cannot be installed on Intel Macs - cannot set EFI boot target error.
2148206 – F37: Bootloader installer fails on early-mid-2010s Apple hardware
They already identified the culprit, and it seems to be fixed in the live-respins as the one you linked.
The 37 beta was problem free, so I hope it does not happen again when they release the 38.
