Paraview 11 installed on Windows 11 is unable to find a reader for vtu or vtk files.  
The file size (unlike previous issues on this forum) is just a few MB. The vtk files have been generated using the vtk library in python.

A sample file has been attached.  
[0000.vtu](https://discourse.paraview.org/uploads/short-url/6uamHYVYXZWse51YdwXFep608Qa.vtu) (1.1 MB)

Your file is invalid and not in .,vtu format.  
It is a .vti

Thanks a lot. The files were .vti but I was saving them as .vtu or .vtk.
