Bugs WaveLab Pro 10.0.10 / 10.0.20

i have no particular details, the problem is that the thing crashes like a stock car. 10.0.20 crashed 2 times in 20 minutes a quite stable session made on 10.0.10. I already reported a gui freeze with Equilibrium on 12th january.
Today was just a montage with 2 effects (sonnox limiter on a clip and limitless on output), no gui opened nor equilibrium involved this time, just skipping the cursor around. The session appeared to be stable on 10.0.10. As usual i’m on a macpro running Mojave. I sent the crash report to Apple then close the software and went back to work. I have the software hanging since to me is actually not usable. Is unthinkable a daw that crashes with clients sitting in the studio. It remembers me the obscure days of windows 95 but in 2020 on OSX.
