Audio files stuttering

So far Cubase10 worked well. Since some days it cannot read the audio files, the sound stops every seconds, as if it was stuttering. I am on Windows10 and the soundcard is BabyfacePro.
Thanks ahead!


Could be a hard drive issue?

It works well with Cubase9.

Because of these audio dropouts, Cubase10 is unusable in my case, and I returned to Cubase9.
