IPTV stopped working after upgrading from 26.4.1 to 26.4.2

[ou1]

As the title says, I upgraded OPNSense Business to 26.4.2 and my IPTV stopped working. I'm not sure if it's an issue with igmp-proxy or something completely unrelated.

The only message relating to igmpproxy in the logs is:
Warning igmpproxy select() failure; Errno(4): Interrupted system call

This message only started appearing after the upgrade.

Any help would be appreciated.
