I have been using paraview on ubuntu for years now and as of today I can no longer view any images. The problem started before I did anything but since I have removed and reinstalled paraview and the same problem persists.
When I try viewing an image I get the following error in terminal.
When I open the file I get a bunch of these in the terminal.
...

In the output messages I get the following lines

Unfortunately, no plot actually appears in the window.
I am sorry that I don’t understand paraview better but if you have any suggestions of things to try I am happy to.
