PDF metadata retrieval stuck in "processing"

edited June 13, 2023
When I try to retrieve the metadata from a paper I just downloaded it opens the "retrieving metadata window" but there is no progress in the processing step. I don't have any idea on how to debug this.
Also, in general as soon as I put a new article on zotero, it automatically retrieves the metadata but for the last 30 minutes I stopped doing so.
Could it be a problem with the latest update?
