Why Cubase is crashing?!

Hello!
My Pro 10 just suddenly crushed, I don’t know why and have no idea what to do.
Here are crush dumps:
Cubase 10.0.40.284 64bit 2019.9.22 0.38.12.158.dmp (757 KB)
Cubase 10.0.40.284 64bit 2019.9.22 0.38.11.887.dmp (698 KB)
Cubase 10.0.40.284 64bit 2019.9.22 0.38.11.705.dmp (663 KB)

Hi,

Unfortunately every single crash is different. Could you try to trash Cubase preferences and rinstall Cubase (as administrator), please?

FYI, I just upgraded from Win 7 to Win 10 and reinstalled C10. It was crashing or Hanging every single close.

It turned out to be MalwareBytes and My Windows Anti-Virus setup. Also, I had a VST that kept giving me an activation popup because I hadn’t activate.

It could have been 1 or a combo of those but my C10 no longer crashes on exit.
