ESP32 kernel panic at random (network_event)

I'm working with an ESP at the moment and I have written alot of code that works on it's own, but once merged, it doesn't.

My code boots, but then I get the following;

09:00:18.780 -> Device is now in pay-mode
09:00:18.780 -> ETH Started
09:00:22.779 -> ETH Connected
09:00:22.812 -> ETH MAC: 3C:61:05:30:A9:7F, IPv4: 192.168.207.102, FULL_DUPLEX, 100Mbps
09:00:22.812 -> Registering Device
09:00:22.812 -> Just the main loop
09:00:23.798 -> Guru Meditation Error: Core  1 panic'ed (Unhandled debug exception)

09:00:23.899 -> 
09:00:23.899 -> Rebooting...

I have no idea what is going on here, or why I'm getting this error. after a couple of minutes, the main loop just runs (so I get the whole time "Just the main loop" in my console.

I'm using an ETH module and I do some API calls. Can this be that the ESP looses power or doesn't get enough power or so? I'm kinda at a loss why I'm getting this error.

The line "Stack canary watchpoint triggered (network_event)" is your cue. It means the stack overrun detection triggered. One of the tasks (named "network_event") has used more stack that it's been allocated. Give it more.
