I think, you have not installed from the Leap15.0-Update Repo: https://download.opensuse.org/repositories/home:/Sauerland:/hardware/openSUSE_Leap_15.0_Update You have updated your system with new kernel but installed the rtl8812-kmp from the OSS Repo, not from the Update Repo. The one you posted at least is also for an updated kernel....... rtl8812au-kmp-default-5.3.4.git20190111_k4.12.14_lp150.12.45-lp150.3.1.x86_64.rpm see xxxxk4.12.14_lp150.12.45xxxxxxxx The 12.45 is the relevant one......
