Both of you seem to have enabled Secure Boot, and that's the known side-effect of the Leap 15.2 kernel. Now it takes more strict Secure Boot lockdown to refuse the unsigned kernels. You'd need to sign the modules by yourself and enable the key via MOK enrollment, or at easiest, just disable Secure Boot in the BIOS.
Optionally, Packman sign the modules by its build server with its own key and enroll that public key onto your system. Or, change the package to do a one-time key generation and implement the MOK enrollment. In anyway, it's the Packman's packaging problem. Please report and discuss with Packman people.
Yes, after disabling the secure boot, the WiFi driver seems to work.
