With IPv6 for most use cases there’s actually more security. With privacy extensions (pretty sure it’s enabled on windows by default), when you make connections from your device, it uses a “private” IP. That is a randomly chosen address inside your network’s prefix, that changes regularly.
These addresses don’t accept incoming connections. You have a main address that doesn’t really change that you accept connections on. Firewall that for ports you want to allow and then hackers need to port scan 2^64 or 2^80 address space to find your real IPs in your prefix. If they capture your IP from a connection to a web server etc, they won’t have luck scanning you.
Again as per my post above, the biggest risk right now is bad default configurations on many home routers.
