Invalid Context= error

[joe at actionline.com]

Just did a fresh install of Mint 20.1 on one of
my thinkpads and have a few issues to resolve:

On my other computer on the command line, I can
type: kwrite file.txt and the file opens fine.

But on this new install, when I type the same,
I see a long list of 50+ "Invalid Context" messages.
Below is just a short example of the first dozen msgs:

Why and what can fix this?
