There is no need to waste any more time on this. We have seen this all
already and it's caused because all ports (latest and quarterly branch) for
FreeBSD 13.x are build on 13.0 currently. But because of an ABI break in
13.1 the wireguard kernel module will panic when used.

Your chances are either rebuild the kernel module on 13.1 and it will work
fine or you wait until packages are build on 13.1 which is VERY soon.

FreeBSD 13.0 is EoL in less than a week (August 31, 2022), so official
package builders will switch soon - the next full build will not have that
problem anymore.
