If the Due doesn't cycle once in 10 seconds it will auto reboot but you'll see on line 235 of controller sketch that it only gets enabled if the web is disabled. I did that because sometimes the web can tie the Due up for over 10 seconds but that can't happen without the web. I just did some more testing with the watchdog and the timer starts fresh when it's enabled so even if it took 30 seconds to connect to router and watchdog still enabled the timer doesn't start till after it connects to router. At that point it would be ok until it went to check for IP and possibly happen then if the server doesn't respond. But with all that said the watchdog shouldn't be turned on if web is enabled and if web is off then there should be no issues.
Can you try the following as I can't replicate the problem.
In the controller sketch comment out line 235 by adding // to the beginning of the line.
Then upload and see if it starts up ok. If it does then go to settings, system and cycle the web enabled setting as there was a minor issue previously so maybe it's causing the issue. After doing that restart the controller and verify in the serial monitor that is says "Internet is not enabled". After that remove the // from line 235 upload again and see if it starts up. If it does enable the web features again and restart the controller (press and hold top right corner) and see if it starts up ok.
I restored 5.20 to original and it rebooted after "Connecting to Router++++++++++++++++++++++++++++++++++++"
I then commented line 235 //if (web.webEnabled() == 0) watchdogEnable(10000); and still the same reboot loop.
