Crash on export

Crash on export. “An unexpected error occurred” error instantly when I try to export my small (first) test project. Mac. The project works fine in the live preview. Works fine with lower poly count fbx asset, not so much with obj file. But as I said, renders fine in the live preview.

Only way out is to force quit. Would have loved to upload my project here, but new user limitation.

Could you upload the project to Google Drive or similar and share it?
