Hello @Sapta0802,

You have already opened an issue in the Sionna repository about the "Can't clean for JSON" issue (NVlabs/sionna#452), as well as on the Colab repo (googlecolab/colabtools#4608). It is unrelated to the mitsuba-blender repository, since the scene export works fine and you were able to render your scene in Mitsuba.
Please refrain from opening multiple issues about the same problem, as you are creating unnecessary work for maintainers of the various repos.

Moreover, "need reply urgent" will not help resolve your problem. Maintainers do their best to assist, but open source projects are typically provided as-is, without any guarantee of support.
