Different SlicerRT behavior when changing Windows to Linux system

I tested the same versions of the software on a Windows system, and it worked successfully. To assist in diagnosing the problem, I am attaching two screenshots of the messages that appear during the display process. These messages do not occur in the Windows version. Could this suggest that the issue is related to the Slicer RT extension on Linux? I attempted to uninstall and reinstall the extension, but the issue persists.
