There was a mixup or mistake and this package got built for Rolling repository at the wrong time. You might see if you run ‘dnf distro-sync’ an option to reinstall kernel 5.7.8. Do not do this.
If you already have kernel 5.7.8 and reinstall it the script will remove your initrd and vmlinuz files and you will not have a boot-able kernel.
Should you happen to have done this boot into another kernel version and remove and install again kernel 5.7.8.
I will be looking into what can be done to correct this.
