Duplicate data after synchronizing photos

Hi, I tried to synchronize all my photo on the adobe cloud. 

All my photos are stocked in my 😧 drive. when I asked Lightroom to sync my photos, it tell me that there wasn't enough space (I thought it needed  temporary space to sync files) so I configured another folder as working folder (G: drive) for lightroom (not lighroom classic) and everything synced well . but now all my photos are duplicated ... what shloud I do?
