Hello,

It looks like dnf configuration issue. Normally kernel is never updated
but installed and dnf keeps 3 latest versions in parallel (the oldest
one may be removed).
I'd try to simplify update to a single package, i.e.
        dnf upgrade kernel-4.18.0-147.3.1.el8_1.x86_64
and see what will happen.
