Mp3 export issue with 11.0.20

Cubase

Since updating to CB 11.0.20 from previous, exporting to mp3 creates a distorted file. The file is ‘phased’ like. Other export formats results are as expected.
iMac Pro 11.2.3

Hi and welcome on the forum,

Could you try in the Cubase Safe Start Mode [Disable preferences], please?

Thank you Martin. It worked. I did as you suggested and opened in CB Safe Mode. The project exported cleanly as an MP3. I restarted with my preferences and the project again exported cleanly as an MP3. Thanks again.
