I found that after I kill he Audio process, Scaler 3 return to the default (empty) state
I can clearly upload the state I saved, but having Scaler less absent-minded 
could be useful, if I forget to save its state
P.S.:
After having set Bitwig to use openGL, and my Nvidia GPU to leave max electric energy to Bitwig and UJAM, it seems I have no more crashes (finger crossed)
BTW, to view the Bitwig’s advanced-settings hidden menu, you have to click on CTRL + ENTER, then write “advanced” in the field search, then click Enter and you’ll see the menu below
