That will be me Sir... u got me scared for a second as the daz->blender workflow is essential for me. Only did daz - blender once to ensure I can get it to work . Tried it again just now and got the same issue , until making the character folder , then saved the scene in the character folder with the exact file name as the folder. Once that was done the export automatically selected the correct folder and saved the file. Additionally still loads it in blender so all is good this is assuming you were able to use Diffeomorphic prior and its not your first time meaning the config/installation was already confirmed successful. If not :-/ that could also be the issue.
