Theta Sticher not working

Hi to all ,
I recently purchased a theta z1 and have been having issues with stitching. I am using adobe lightroom classic to export the image in tiff format, but when I drag it into the stitcher it shows a preview of the image already stitched but when I press ok to save , It starts processing but then comes an error stating that the image could not be processed succesfully.
I am using windows 10, 12g ram laptop.

I’m not familiar with this problem, and I don’t own Lightroom. But in case you didn’t see it, there was an older discussion with @CorLeone and others talking about images not being processed correctly. Possibly there is some useful information in the thread.
