Random crash Cubase 9.5.550

Hi,
I have a MacBookPro with MacOS 10.13.6 (High Sierra) and Cubase 9.5.50.
Sometimes it crashes. Few days ago I have formatted my MacBook an reinstalled MacOs and Cubase, but last night Cubase crashed again.
As attachment the crash file from my Utility Console.
Any suggestion?
Thanks
