I'm trying to export feature classes (tested shapefile too) to DGN and I keep receiving this error. I've tried exporting a smaller subset of features, moving them to a different database, and exporting as DWG. I've also tried checking and repairing geometry (there weren't any).

Did you create a featureclass in a locally stored file geodatabase as the source file?  It sometimes corrects geometry and/or topology issues.

Yes all the data is local.
