You tried the exe also? (not only the cmd)

I am having a similar issue. When I try to load DNG from my DJI Mavic 3 and I try to save the keyframes, the visual preview start looping and are not saving the metadata. When I try to open this in LR does not recognize the keyframes in the filters. Also glitch the program graphics. I am attaching a small video. Unlisted. https://youtu.be/pGdtjDf_Tf8

The first part is totally unrelated to the topic of this thread.
Basically in your video you can see that you get a warning about timestamps being in the future, you ignore that warning and don't fix the timestamps and then you wonder why the visual previews don't work.
So: let LRTimelapse fix the timestamps, you can trigger that manually via "Metadata / Shift Timestamps". Then you will be able to work with that sequence. Set the date in your drone to match your computers date/time to avoid such problems in the future.

The graphic glitch at the end could be related, so please try the alternative launcher from this thread.

I will open another topic with this issue.

First try the provided solutions, please...

I can confirm those glitches on Macbook M1Max. Often a restart helps to restore the interface.

Do you get any errors in the log after that happens? The log will be in the Folder Documents/LRTimelapse - it's called "LRTimelapse.log".

The alternative launcher "noD3D" for Windows is now included in the 6.0.0 release version.
If anyone experiences graphic issues please use that launcher. It will be installed in C:\Program Files\LRTimelapse 6
