CPU usage spikes to 100 and then WAN disconnects.

Hello all.
I have been attempting to reconfigure my network and this is my first time using OPNsense, I am using a Protectli FW2B, 2 port vault for this.

Now as the title implies not everything went smoothly.
I installed the device just fine and configured everything, and after placing it in my network everything appears to be running smootly for about 20 seconds, before I start running into the issues.

Network connectivity is fine, all devices connected without issue.
However the device ends up spiking to 100% CPU usage even though its neutral state is around 10-20.
While this happens the WAN connection drops and thus I cannot connect to websites on any devices anymore expectedly.

I am not sure how to debug this and could not find any information anywhere.

This is my current set up;
WAN -> Regular Starlink connection which is connected to the router and not in bridged mode (Yet).
LAN -> TP-Link Deco Mesh.

These issues do not occur when I have WAN connected to the TP-Link Deco Mesh, however in all fairness less devices are connected in that state too.

If any of you have any ideas of what I might be able to try that would be lovely.
