NTM Version:1.0.27X4445
This morning, while trying to make spent nuclear fuel reprocessing, one of the conveyor sorters crashed the game while entering a double-link fuel rod.
By analyzing the crash report, I found that this seems to be an issue with the sorter.
Subsequently, just as I tried to enter this save again, the game crashed again.

Do you have the actual crash report?

This is another crash due to Conveyor Sorter

Should be fixed in X4480, although since I can't replicate the crash I don't have any means of verifying it.
