**SOLVED ISSUE*** : If you have anything similar it might help if you Disable or Unistall the FreeU Advanced Node. I did so and viola issue solved!

[Theodor800]

Thank you very much! Uninstalling FreeU helped to solve that but now it gives "Conv3D is not supported on MPS" error. You know how to solve that? :)

[sergcbravo]

Sorry that one i'm unfamiliar with.

[Theodor800]

No worries. I read it's some Mac issue and svd doesn't work with Macs yet. Have to wait for next updates....

[Zlata-Salyukova]

This was my issue on Windows11, unstalling "FreeU" custom nodes fixed the Ksampler from erroring out.
