      I don't even if know if this will fix grub or not. But here you go.

      Create a new empty grubenv file in /boot/efi/EFI/fedora/grubenv.

      sudo grub2-editenv /boot/efi/EFI/fedora/grubenv create
      

      I noticed on my system, there is a symbolic of /boot/efi/EFI/fedora/grubenv in /boot/grub2/
      74e0d7c8-c3eb-40ce-a0ec-0bd242206235-image.png

      sudo ln -sf /boot/efi/EFI/fedora/grubenv /boot/grub2/grubenv
      

      Rebuild GRUB

      sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
      

      Rebuild initramfs images

      sudo dracut --force --regenerate-all
      

      And then reboot.

      Actually, the /boot/efi/ folder was completely empty. No sub-folders or anything.
      I made EFI/fedora in there and then the commands ran.

      But no change in behavior

        @JaredBusch got a backup that happened to grab /boot...?

        Or maybe copy what's needed from a working system?

          No backup since the data is sync'd.

          Mostly I'm trying to figure out how to resolve without a reinstall if possible for knowledge sake. Not to save my system.

              Had to be, as it was working. I shutdown to go home. Then it wasn't working.

                  Unless someone has any more ideas, I'm also out of ideas and I will have to reinstall since I will need my laptop on Wednesday and Thursday.

                    Kernel 5.3.12-300 is current.
                    But both previous kernels fail also.
                    5.3.11-300
                    5.3.8-300

                    So this suggests that a library or something has failed, not the kernel. That's going to be a huge pain.

                      Right sounds like the grub update borked itself.

                        Can't provide any input but it's interesting to read the problems that shows up every time there is a new Fedora release out. Your customers are a forgiving bunch for sure.

                        That said, it's great for the open source community to have lots of people running the latest and greatest. 👍

                        I've been on Fedora about 2 years on my laptop now and I know exactly what you're talking about.

                        No new release issues on any Fedora system that I use, either. Been flawless and we use it across laptops, desktops, and servers.

                          I did have a Fedora 31 laptop (different model Dell than mine) spun up and logged in two weeks ago. I have ran updates on that one and rebooted. it is running fine.

                          Yeah, my Dell with F31 hasn't had an issue yet and I keep it updated.

                            The updates show that grub had changes. Shit happens with all OS.

                            They also showed that something new was being compiled against GLibC and the Kernel.

                              That's definitely my guess.

                                @JaredBusch have you tried the boot loader rebuild process listed here?

                                  I don't have any internet. It only boots to emergency mode when I choose the rescue kernel. Anything else is the boot loop.

                                    What about booting to a rescue USB stick?

                                      I can boot to a live USB. try it from there you think?

                                            managed to boot into recovery mode and get an IP from a USB ethernet dongle.

                                            I ran through the instructions fine on that link, but then step 5 was a link to another page that stated to run grub2-install /dev/sda

                                            Well that puked on the nowEFI thing. Google told me I needed to dnf install grub2-efi-x64-modules.

                                            Now it dies and says grub2-install: error: cannot find EFI directory
