Hey,
I updated Cubase 15 from 10.5 and when i open the Application from within the Application folder on my macos it directly crashes within seconds.. So i opened Cubase with the command sudo nohup /Applications/Cubase\ 15.app/Contents/MacOS/Cubase\ 15 && sleep 3 &>/dev/null &
Need to enter my admin password and everything seems to work.. Cubase 15 loads all the plugins and all seems to be working and i can close the terminal window. But everytime when i want to open the Application from the dock it opens up and it terminates instantly.. So could someone look at the crash dump file and look if there may be some issues?

Cubase seems to start normal from dock when i use it in Safe Mode so i guess it is third party vst plugin related. And i guess it is ownership/permission related aswell.. 
Hi,
Reported to Steinberg. Thank you.
Hi,
Which option exactly did you choose from the Safe Start Mode window, please?
Deactivate all third party plug-ins + Use current program preferences.
So i have been using Cubase 15 for some days now and i really love it!
Still using a terminal shell script to open cubase as sudo because whatever i do or try it instantly crashes when i open the Application from dock. I also tried to export and cubase crashes instantly though.. also as superuser..
#!/bin/sh
sudo sh -c 'nohup /Applications/Cubase\ 15.app/Contents/MacOS/Cubase\ 15 > /dev/null 2>&1 &'
I am pretty aware that running the program as superuser is not the way to be but i could not resist to produce music in this new huge update so i did anyways..
Here is the most current created crash file. I hope somebody can look at it because i have no idea where to look for in this crash log. XD

Hi,
The crash is in the SlinkFilter plug-in:

I removed the SlinkFilter plugin and noticed in a previous log that Halion Sonic SE crashed so i removed Halion temporary to see if i can open Cubase normally but still crashes. This is the log directly after the crash.

So i am adding all VST3 plugins back inside of the VST3 Folder to see exactly which ones causes problems. I deleted all the VST3 plugins and restarted and so did Cubase start normally. So there must be some old plugins causing the crash on startup because it seems that the vst3scanner is crashing while scanning. Will report back later.
