This is all I was asking you to check. See the PARTUUID in the output
of blkid? PARTUUID="14c4ac1d-abd8-4121-84ee-c05a825920de"
It matches the UUID of the boot entry:
HD(2,GPT,14c4ac1d-abd8-4121-84ee-c05a825920de,0x145800,0x6400\0)/File(\EFI\centos\shim.efi)
I do see you have 4 separate boot entries for Linux (one oddly called
fedora despite using the CentOS shim), you might do well to narrow
them down to just one.
(efibootmgr -B -b <bootnum>)
If your BIOS has the ability to choose to boot from a file, I suggest
giving that a try, and try both /EFI/centos/shim.efi and
/EFI/centos/grubx64.efi. Perhaps one or the other isn't working
anymore.
