Welcome to the forum @Home-kia

For the invalid context file it sounds as if it is corrupt. The easiest solution is to delete it (or move it somewhere in case you decide you want to get something out of it, if possible. Alternatively have a look at it and see if you can correct the error.

That means you have installed two nodes that conflict, and should remove one of them. To do that if you go into the folder where you flows file is (I don't know where that will be if you are running the HA addon) and run
npm remove node-red-contrib-s7comm
or the other one, then restart node-red.
Having said that HA may have a special method for defining which nodes to install, in which case use that method to remove it.
