Error in interactive Blender container

[melomcr]

When trying to run the interactive Blender container documented here, and using the indicated command:

$ singularity exec --nv blender.sif blender

I get the following error:

Authorization required, but no authorization protocol specified

GHOST: failed to initialize display for back-end(s): ['X11']
  'X11': unable to open a display!
GHOST: unable to initialize, exiting!

The container works as expected for a non-interactive command:

$ singularity exec --nv blender.sif nvidia-smi

I would appreciate any help debugging the issue.

----- EDIT

I should add the very relevant info that I am running Fedora 40 with KDE/Plasma, meaning I have Wayland running my desktop. Theoretically it still supports X apps, but I wonder if this could be the source of the issue.
