After searching for a long time, I found that there is indeed a very good way to repair PDF files under Linux. Combining the two methods, the effect is better:

mutool clean bad.pdf good.pdf

The exported file has been basically repaired Pretty much the same.

pdftocairo -pdf good.pdf best.pdf

This way you can export a pdf file with better recovery effect. Of course, there is no guarantee that 100% of the content can be recovered.
