Kernel Error after update of Anaconda-Navigator

Last week I received a msg that there were updates available. So, I updated. This gave rise to several problems - as follows


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
