I've renamed the topic to better match the actual problem.

Yes please - that will allow us to see if there is anything unusual with the Flac files.

So I presume that previously you did not have this problem?
What changed?
You upgraded from an earlier version of Audacity?
Are you using Flac files that worked ok in an earlier Audacity version or are these new Flac files?
What was the earlier version of Audacity?
Where do these Flac files come from? Do you encode them yourself? Are you using the same encoder that you have always used?
Is this on the same computer as you used previously?
Has anything else changed or been updated?
