Hello.
This happens for every operation after an upgrade from gentoo-sources-4.15.0 to gentoo-sources-4.20.0:

Code:

# nft add table filter
Error: Could not process rule: Operation not supported
add table filter

# nft flush ruleset
Error: Could not process rule: Operation not supported
flush ruleset
^^^^^^^^^^^^^^

Here's emerge --info nftables:

Here's kernel's 4.20.0 config file:

You've disabled IPv6 nftables support in the kernel, so you need to explicitly say you want a single-stack ipv4-only table instead.
