I updated to 15 from 14 about 2 weeks ago and have been experiencing this issue on loading projects. I select the project from the HUB, and Cubase starts loading but stops. The Task Manager shows this:
Projects are both existing (from 14) and newly created in 15.
do you get any dmp files in your crash files folder? does it happen with all projects or just some?
No dump files. It just kinda freezes. Seems to happen on every project but not regularly. I usually reboot the machine and try again. It typically works then.
If it is always on loading a project, it might of course be a rogue plugin. I would suggest starting Cubase in safe mode
But select “disable third party plugins” instead of “disable preferences” (you can do that, too, if it turns out not to be a plugin).
FWIW, if you want to have a process dump to report for an app that has locked up but has not crashed, you can get it from task manager.

Thank you, Pete. I did not know that.
Just ran into the same problem as above: C15 working fine all day and suddenly not responding anymore. FWIW: I was changing an output of a midi instrument from VE Pro (Synchron instrument) when it happened. PC explorer became (partly) unresponsive as well e.g. I can’t type anything in the searchfield in the Taskbar anymore.
Working on pc: W11, 64GB of RAM, i7-12700k, MSI Z790-P motherboard, all software on fast SSD’s.
Dmp file is in the attachment, I hope you can find something useful in it.

so Vienna Ensemble Pro would be the problem
Hmm, that would be a problem, this whole template is built around VE Pro… 
I’m running the latest version of VE Pro, I also have some music in templates without it, but this one is with it and is a quiet important one (long scene in movie).
D*mn, have to look into how to fix this
I think several users report this plugin as problematic. I guess contact the vendor, I do not use this instrument
Will do this. Thanks for your swift replies!
Is VEP allowed through your firewall?
The text from the dump above indicates that it’s waiting on the socket. That could mean it’s blocked, or you have other network issues. Ensure it’s a wired connection and shows up as private/trusted, not public, on both PCs.
