Here’s 3 of my crash logs from the last 3 days with 3 different plugins.
Mine crashes a lot when I close projects and then try to open them again. The project doesn’t open and Cubase just crashes. I’ve found the in hub if I select “Open Other” and select the .cpr file that it will usually open, but that shouldn’t be the case???
You can also see from the attached image that this happens frustratingly often compared to other programs
