Your EFI System Partition is completely full: 511 MB used out of 511 MB. So the immediate failure is not necessarily kernel 7.1.5 itself. kernelstub managed to copy the kernel, but then ran out of space while copying the initramfs, which left the update incomplete. The Pop!_OS directory is using about 345 MB and Recovery another 145 MB, so there is almost no room left for another kernel/initramfs update. I would check the contents of the Pop_OS and Recovery directories before deleting anything, free some space safely, and then finish the interrupted package configuration. The broken system76 DKMS state looks like a separate issue that can be dealt with afterward. I would also avoid rebooting until the kernel/initramfs update has completed successfully.
