Pitch shift causes super-loud metallic glitch at start of audio segment

Windows Cubase Pro 10.0.20: this has already happened several times after the upgrade to Cubase 10 Pro. Once in a while, Pitch shift causes super-loud metallic glitch at start of audio segment.

Please see the attached screenshot - the glitch as at the start of the selected audio segment (it’s a quiet flute part, nothing radical in it).

Please fix this.

Thank you!
