"Unable to adjust the sampling frequency, the clock may be set to external synchrony."

Hello, good evening, everyone.
I use the cubase program to mix my music, which I record at home.
I have already recorded and exported several projects and I have never needed to reopen a project. Today when I opened it, I got a message saying:
“Unable to adjust the sampling frequency, the clock may be set to external synchrony.”
Now I can not open any of my projects, they all come out distorted … I want to edit voices and I can not.
Can someone help me please ?? I’m pretty overwhelmed. the frequency of the plate and that of the program is the same. I use the TRI-CAPTURE plate
thank you
