The google search console revealed to me that none of my pages was indexed, all pages are listed in the 'excluded' section "duplicate, google chose different canonical than user".
But in the URL-inspection tab it shows me
google-selected canonical: N/A
Indexing and crawling is both allowed. Don't know how to get my pages to be indexed correctly. (by the way, they do NOT exist in other languages, so that can't be a reason why google might think they are a duplicate. There's definitively no other version of those pages available)
