Kernel Error after update of Anaconda-Navigator

I chased around for a solution and eventually deleted Anaconda-Navigator from my system and did a re-install. That is when I got the Kernel Error

From what I can see there is only one kernel. How do I resolve this or at least get a better idea of what the problem is

Thanks in advance
