Stuck notes on export

MuseScore 4.0.2 on Windows 10. Score looks just fine, playback inside of MuseScore is perfect, but when I export to .WAV there are all sorts of stuck notes that don't drop when they should. It's not an orphaned tie, because there are no ties for several hundred measures (it's very staccato). And, like I said, it plays perfectly inside of MuseScore. Has anyone else had this problem?
