Babel doesn't work after reboot

[asdfjkluiop]

Describe the bug
Upon a reboot the frr log will show a message like
babeld[1308]: [ZPCFR-WY2XV][EC 100663299] setsockopt(IPV6_JOIN_GROUP) on interface 'enp6s0': Address already in use
and babel will never initialize requiring a restart of the frr service in order to come up and establish neighbors with other babel routers in the environment.

• Did you check if this is a duplicate issue?
• Did you test it on the latest FRRouting/frr master branch?

To Reproduce

1. Setup babel
2. Reboot machine

Babel config used in my setup:

interface enp6s0
    babel wired
exit
router babel
    network enp6s0
    redistribute ipv6 connected
exit

Expected behavior
Babel should correctly handle this situation on reboot and successfully exchange routes with other neighbors. I get similar warnings from ripngd however it has no issues exchanging routes after a reboot.

Versions

• OS Version: Debian 12 bookworm
• Kernel: Linux 6.3.3
• FRR Version: 8.4.2

Could you tell us at least the configuration and how to reproduce this with some easy steps?

[asdfjkluiop]

I've updated my post with the config I'm running, I originally left it out because it's about the most basic babel configuration you can run. Let me know if there's any other information I can provide.
