File is '[Anime Land] Sleep (2023) (BDRip 1080p HEVC EAC3) KOREAN [BA382261].mkv'
I have '[Anime Land] Sleep (2023) (BDRip 1080p HEVC EAC3) KOREAN [BA382261].nfo' in the same folder with content 'https://www.imdb.com/title/tt8209702/'

What am I missing?

For some reason Kodi cannot see the nfo file. Instead it is trying to look up the movie directly.
But because you have changed the name of the movie, it can't be found.
debug <general>: using title of [anime land] sleep to find movie

It is not logged why Kodi is ignoring the nfo file. Maybe a wrong character in the filename so it is not identical with the video file name? Maybe the file is not in UTF-8 format. I can't tell.
Maybe remove the [Anime Land] prefix?

Tx.. must have been something like that. I was playing renaming the names of both files and kept working, at the end I came back to the original name and still worked.
