6.4.0 - Application Error when exporting intelligent playlists to USB

Hi

I migrated my collection from Rekordbox 5.8.5 to 6.3.0 then upgraded to 6.4.0.

Then I tried to export my library to my USB stick and Rekordbox crashes with an "Unexpected Application Error".

After some trials an errors I'm certain it's caused by the Intelligent Playlists I've got somewhere in the folders tree.

• If I export a tree with no intelligent playlists, it's fine.
• If I move the intelligent playlists elsewhere then export the tree, it's fine.
• If I export a single intelligent playlist, it crashes

I've read some time ago there's a an issue related to a tag we can reset somewhere. Can you help me ?

Regards.
