I'd check the dkms build logs in: /var/lib/dkms/v4l2loopback/${V4L2LOOPBACK_VERSION}/build/make.log (replace ${V4L2LOOPBACK_VERSION} with the version you have installed, it looks like it is 0.12.5 from the repo) Looking at the issues in the upstream git repo, it appears to be an issue with the version of GCC not matching the one used to build the kernel. The suggestions were to run 'dnf downgrade gcc' before building. Not sure if that helps.
