macOS Mojave

I hsve been using the Multi-encoder for years to rip FLAC and MP3 for a cd at the same time - all good

Until last week...the Path is greyed out and it rips (makes a noise, shows progress in CD Ripper) but the files can't be seen in the usual folder. If I specify just MP3 or FLAC its fine, the ripped files show up

My OS has remained unchanged in this time

Please help, most frustrating!
