Reproduce the failure by running cachyos-installer and selecting Install Base Packages on the reported HP zBook Ultra G1a setup. Start with coredumpctl and coredumpctl info for the cachyos-installer crash, then map the reported executable offsets to the C++ source. Done means the installer completes this step without a segmentation fault.
