The APNX file may be unusually small compared to the original file. This is most often caused by a problem while downloading the APNX file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online.

The program indicates that the file is encrypted or corrupted. The encrypted APNX files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the APNX file to another location.

Sometimes you have to wait for the session to the file APNX to close. However, some background programs may block the APNX file while scanning. If the problem persists, restart the machine.
