In short, the recipe saves the various NumPy files using the lowest possible data type without compromising accuracy, in order to reduce disk space usage. In your case, the issue occurred during the UTCI matrix calculation. The air temperature file used in that step was saved as float16, which led to overflow issues later in the NumPy calculations. I suspect the annual/monthly analysis worked because the same file was saved as float32 at th…

Particularly because your component versions are older for 1.9 instead of 1.0. Try installing LBT 1.10 and then running the Versioner to see if that solves your problem.
