I don't know if it's related, but all of our dual-boot workstations
that used rEFInd for the boot selector stopped being able to launch
the shim EFI executable after upgrading to the 7.6 shim.  I had to
manually change the refind configuration to point at the GRUBX64 EFI
executable instead (we turn off secure boot anyway, custom kernel
modules).
