When I try to initiate an export from Lightroom and attempt to select the destination of rendered folders, Lightroom freezes and requires a hard close (Task Manager). Windows. Happening with both version 5.8 and version 6.0. Lightroom functions as expected when I export without the LRTimelapse involvement.

Could you please send me the LRTExport log, after that happens? You'll find it in the Documents\LRTimelapse folder. You can paste it here.
