Even, if the interface doesn't work, you can just trigger the rendering of the preexported intermediary sequence in LRTimelapse manually: Choose File / Render Video, make sure the render dialog is in the Mode "Render Preexported Sequence (Lightroom)" and then click on "Choose" to select the exported LRT_* folder whith the preexported intermediary sequence.
To get the interface going:
Gernerally: Lightroom and LRTimelapse need access to the folder Documents/LRTimelapse. Make sure that no Virus Scanner or other "Security Software" is blocking them from access (whitelist both programs). On Mac allow "Full Disk Access": https://forum.lrtimelapse.com/Thread-how...pse-on-mac
If the Problem persists, go to your Documents folder, there should be a "LRTimelapse" folder inside. Delete it. Next time the hand over from Lightroom to LRTimelapse should work again.
