Hello,
i'm fairly new to the platform and the whole ai training procedure, but i had an idea in mind and i wanted to try it out. so i followed the tutorials i could find and the documentation, i correctly isolated the vocals and hashed the audio with Adobe in 9 separate files of less than ten seconds, linked correctly the files folder into the web-ui, but upon clicking on Start Processing, i caught some errors in the CMD that i haven't seen popping up anywhere else, so here goes :

2024-01-01 16:57:39 | ERROR | root | Task exception was never retrieved
