Hi – I’m not sure what to advise but I strongly suspect that both of you use Tascam gear is no coincidence. I think I have US-224 that I can dig out andf hopefully reproduce.

In the meantime could you try the following for me:

proceed as above but instead of starting to play the project back please re-confirm your Audio device and buffer as a first step. Then try to utilize as normal. btw what do you mean by play back the project, are you using EZplayer pro?

Anyway if the above still crash and burn your system can you open a support ticket referencing this topic and we’ll be in touch to have a look remotely and try to get to the bottom.

I’d prefer that only one of you follows offline.
