This restricts your wan6 to obtaining its IP address via RA / SLAAC. DHCPv6 will not be used except for a prefix. If the ISP has changed to using DHCPv6 only, you will not get an IPv6.
Removing reqaddress and reqprefix restrictive configuration will try both RA and DHCPv6, thus is compatible with more ISPs. This is the default.

I've tried it, it seems to still not have ipv6.

If it helps, I also installed AdGuardHome on my router. This is my yaml file.
