Pages file won’t open

While typing in a Pages document (saved in iCloud Drive) using my iPad, the app froze and crashed. Since then, Pages won't open that specific document, though other documents open without any issues. When I try to open the document, it keeps loading, and after a while, the app crashes. I can temporarily open the document by clicking "Remove Download" first, but this only works once. I made a copy of the document, which opens without any problems. However, I can no longer open the original document on my iPhone either, as the app crashes there too. It seems like there's an issue with the document itself. The document is 157 MB, but that doesn't seem to be the problem, given that the copy works fine.

Both my iPhone and iPad are running iOS 17.5.1.
