trouble in reading file and plotting

[Aytekin çıbık]

Dear Fenics community

I am a new user to fenics and facing some problems at my first attempt. As you can see from the attached snapshot, whenever I try to run a script which reads xml files, I get the same error message. Also plotting does not work. It gives an html address which is not working, however, solution files are saved into the directory correctly.. I face the same issue on both docker containers in windows system and ubuntu versions (wsl on windows).

Your help is much appreciated.
