Silicon Labs Multiprotocol OTBR Firewall issue

Hello everyone,
I ran into an issue while setting up Matter/Thread using HA Supervised and SkyConnect:

I am unable to add a Matter over Thread device (Aqara P2), because it fails to connect. To solve this issue, I have seen multiple posts suggesting disabling the OTBR Firewall within the Silicon Labs Multiprotocol Add-On. When doing so however, the add-on fails to start entirely repeating the same 3 lines:

[18:00:07] INFO: OTBR firewall teardown completed.
[18:00:07] WARNING: otbr-agent exited with code 3 (by signal 0).
ip6tables v1.8.7 (legacy): can't initialize ip6tables table `filter': Table does not exist (do you need to insmod?)
Perhaps ip6tables or your kernel needs to be upgraded.

Has somebody already encountered this or knows a fix? (I have already tried fixing the iptables issue, but without success) Thanks!

I have the same sensor and the exact same issue. Did you manage to get a solution?
