Solution:

Redownload the file: If the file was downloaded from the Internet, try downloading it again and make sure the network connection is stable and uninterrupted during the download process.

Verify file integrity: If the download source provides a checksum (such as MD5 or SHA1), use a checksum tool to verify the file integrity.

Use other decompression tools: Try using other decompression software (such as WinRAR, PeaZip, etc.) to decompress the file to see if it can succeed.

Check the storage media: If the file was decompressed from a local storage media (such as a hard disk or a USB flash drive), check the health of the media and use a disk check tool (such as the Windows chkdsk command) to scan and repair file system errors.
