@Will. @pwalpwal I did a few tests and I think this problem has to do with both the sound card and the thermal Because when I delete/bypass the thermal, there is no crash On the other hand, when the thermal is enable and I unplug the sound card, there is no crash And another important point is that when I bypass the thermal and export without any crashing ... after exporting, I want enable the thermal .. by enabling it, Daw crashes( in this situation sound card is plugged)
