Could you help me?

I installed newest JAVA, Lightroom Classic and LRTimelapse 5.7 on my windows 10 laptop. But, I can't use LRT Export 5 on Lightroom.

Error message are bellow.

On Export window.
Can't Use Plug-in "Export Time Lapse (LRTimelapse)"
Could not load the post-processing filter from this plug-in.
More information about this plug-in may be available at the following web site:

On Plug-in Manager window.
LRT Export 5
Status: This plug-in is enabled, but has encountered some problems.

How to disolve this problem?

Restart your computer and try again.

I tried restart already, but the situation did not change.

I found one more error message on plug-in manager window,
LRTExportDialogSections.lua:31: attempt to concatenate a nil value
Is this a clue to the solution?

Which version of LRTimelapse are you using? There is no version 5.7.
The latest official version is 5.2.2.

But anyway: the error happens, because of a misconfiguration in your Windows system.
There doesn't seem to be a default "documents" folder defined in your windows system. You might want to google on how to fix this. See this thread also: https://forum.lrtimelapse.com/Thread-lua-sadness
