FWIW there were a couple reports like that with a previous version of SpectraLayers, also when applying an AI process. The AI processes in SL10 are very different from AI processes in previous versions of SL (both in term of models and libraries), but all those AI processes have in common is to use all your CPU threads at once rapidly to the max (FYI Noisy Speech is not yet GPU accelerated).
It was rooted that the cause of the shutdown was the CPU not being properly configured to handle this sudden burst of power.
The solution at that time was changing a BIOS setting so that the CPU could handle the sudden burst of power required by the AI processes: SL Pro 8 - Crash on Unmix Stems - #2 by Robin_Lobel
