When the application opens a PDF, traverses and builds the annotation elements related to hyperlinks, it fails to validate the abnormal annotation relationships and field combinations. This results in the internal objects entering an invalid state. Eventually, during the destruction phase, an invalid pointer write occurred, causing the application to crash.
