Hi, i recently moved up to cub 15 from 14 on windows 11 set up, my system was ok for a while but now it crashes soon after start up, i have launched it with no 3rd part plugins and it still crashes. i have attached a couple of the crash dumps
Cubase 15.0.20 64bit 2026.4.16 19.34.27.125-freezedump.dmp (1.2 MB)
Cubase 15.0.20 64bit 2026.4.16 19.30.35.061-freezedump.dmp (1.2 MB)
hopefully someone can analyse and suggest what the issue might be. Does steinberg offer any help in looking into crashdumps? If not then it would help if they did and it may reduce the number of queries on this forum. I hope someone can help thanks.
In both crash dumps, I see the KORG USB driver installed.
KORG (and Microsoft) recommend uninstalling them.

If that doesn’t do it, we have more complete instructions for removal on the Windows MIDI Services Discord server Windows MIDI / Audio

Hi, thanks for that Pete, my setup is ok again. I had a look at the crashdumps with wdbg and I didn’t see anything about korg driver, I know this is a complex programme but I think some basic things to try would help a lot of cubase users. Whatever you did, it was the right solution for me. Thanks again.
Glad that helped.
The KORG driver didn’t show up in the stack trace, but I saw it in the loaded modules. It’s “KORGUM64”
the command is lm
