Cubase 8 has stopped working when quit

I’ve been using Cubase 8.5.20(64 bit) on Windows 10 for a long while and it worked so well.
But today, when I quit Cubase, a message box pops up and shows “Cubase 8 has stopped working”.
I try several times and it turns out to be the same result.

Operations:

  1. Run Cubase as administrater.
  2. After Cubase being started, open no projects, just click File->Quit.
    -> Result = The message box pops up (crash).

Whether open/new any project or not, the same result.
I try “Disable program preferences” and then choose “generic low latency ASIO driver”, the same result.
I disconnet my audio interface and operate as steps above, the same result.

I’ve actually started experiencing this same issue! I’ve been using 8.5 Pro for a while and whenever I close one specific project it crashes every single time now. The only difference in the new project versus the others is I’m running VST instruments. In my other projects I just have guitar/bass/drums/vocals and nothing VST related.

I’m running Windows 10 and have Cubase 8.5.20 (64 bit) as well.
