The execution time of +[APMAEU isFAS] suddenly increased significantly

[sunhr]

Description

Our app's startup time significantly increased starting around 0:00 UTC on October 17th. Using the Launches Report feature in Xcode 16, we found that the execution time of +[APMAEU isFAS] began to spike during the same period. Due to the app release, the subsequent data after Oct 17th can be ignored.

However, we noticed that the execution time decreased back to its original level starting on Oct 22nd. Do you know what caused this increase in execution time?
