Resolved by updating userspace.

I can reproduce this error on non-production machine and found this
error is resolved by re-bulding updated nftables, libmnl and libnftnl:

With these versions nft rules now load without error:

 - nftables commit de904e22faa2e450d0d4802e1d9bc22013044f93
- libmnl commit 54dea548d796653534645c6e3c8577eaf7d77411
 - libnftnl commit 5c5a8385dc974ea7887119963022ae988e2a16cc

All were compiled on machine running 6.19.4.
