Added a group track, project freezes when opening

Hi!

Cubase Artist 9.0.40

I added a group track to my project and routed 8-10 tracks from Groove Agent to the group track.
Insert filter on the group track and everything was working fine.

I save the project and try to open it a few hours later. Cubase freezes while loading the MixConsole.
Strangely it freezes loading Channel: Out 14 (which was not added to the group track).

Any suggestions?

Thanks!
