A typical compatibility error - the program does not support the older version of the XLST file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair XLST file corruption. You can restore the file from a backup or use help.
The program can also signal the fact of encryption. The encrypted XLST 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.

If the error persists after closing other programs, wait for a while. However, some background programs may block the XLST file while scanning. If nothing helps, please reset the device.
