Seems to reproduce regularly on my end.

Steps To Reproduce:

  • Create a material, ensure it has a texture sampler somewhere in it.

  • Play around for a while (seriously).

  • ‘Preview’ the texture sampler node.

  • Plug something into the emissive channel input.

  • Receive following crash:

    !Id:c87a4f3d7a5d659fb91c8aa4bafe74fd

    Unknown exception - code 00000001 (first/second chance not available)
