I have the same problem on all of my systems, running the same package
versions and kernel, also under 7.5:

libsepol.policydb_read: policydb version 31 does not match my version
range 15-30
invalid binary policy

3.10.0-862.2.3.el7.x86_64

policycoreutils-2.5-22.el7.x86_64
checkpolicy-2.5-6.el7.x86_64
selinux-policy-targeted-3.13.1-192.el7_5.3.noarch
policycoreutils-python-2.5-22.el7.x86_64
selinux-policy-3.13.1-192.el7_5.3.noarch

sl-release-7.5-2.sl7.x86_64
