Error message

{profileFileInfo.Path} could not be found!

What it means

Load was asked to read a profile file whose FileInfo no longer points to an existing file on disk (deleted or moved after startup/enumeration). Legacy XML files that vanished are tolerated (migration path just logs and removes the entry), but for non-legacy profile files the missing file is treated as an unrecoverable state and a FileNotFoundException-style error is raised from Load, which Save also triggers when it reloads before writing.

Solutions

  1. Verify the profile file exists at the configured path (File.Exists) before loading or saving.
  2. Restore the profile file from backup or re-create it if it was deleted externally.
  3. Correct the profile file path in the application settings if it points to a stale location.
  4. Check for external processes (sync tools, antivirus, cleanup scripts) removing the file while the app runs.
