The first thing that comes to mind when the above error occurs is Baidu, because there are no "hundreds" of failures that only you can't think. It may have entered a misunderstanding at the beginning.

Select "application pool" on the left, select "Classic. netapppool", and click Advanced Settings on the right to change the ID to LocalSystem or NetworkService.

According to the above description, the application pool has been modified, and my problem remains unsolved.
