[Bug]: uefi install failed `add_additional_entries_limine`

### Kernel

?

### Desktop Environment / Window Manager

KDE Plasma

### CPU

Amd ryzen 1600

### GPU / Driver

Nvidia GTX 1070

### Description

Error on install with default settings.

### Steps to Reproduce

Install cachyos-desktop-linux-260426.iso with the defaults

### Expected Behavior

It would install the bootloader or at least tell me an understandable error message and maybe give me an option to try some workaround (maybe a different bootloader).

### Actual Behavior

Incomprehensible error message.
Only option, start over, guessing at what to do differently.
