Solutions

1. Verify the file exists at the exact path provided (check for typos, case sensitivity on Linux).
2. Use an absolute path to avoid working-directory ambiguity.
3. Check that the application has read permissions on the file.
4. Log or print the resolved path before calling ParseFile to confirm what path is actually being used.

Example fix

// before
var strategy = JsonCombatStrategyParser.ParseFile(relativePath);

// after
var fullPath = Path.GetFullPath(relativePath);
if (!File.Exists(fullPath))
    throw new FileNotFoundException($"策略文件不存在: {fullPath}");
var strategy = JsonCombatStrategyParser.ParseFile(fullPath);

// Validate file existence before parsing
var fullPath = Path.GetFullPath(strategyPath);
if (!File.Exists(fullPath))
{
    Console.Error.WriteLine($"策略文件不存在: {fullPath}");
    return;
}
var strategy = JsonCombatStrategyParser.ParseFile(fullPath);

try
{
    var strategy = JsonCombatStrategyParser.ParseFile(path);
}
catch (FileNotFoundException e)
{
    Logger.LogError("找不到策略文件: {FileName}", e.FileName);
    // Prompt user to select a valid file or check the path
}

When it happens

Trigger: Calling JsonCombatStrategyParser.ParseFile with a path that does not exist, a relative path resolved from the wrong working directory, or a path with a typo in the filename or directory.

Common situations: User configures a custom JSON strategy path that is wrong, moved, or deleted. Also occurs when the path is relative and the application's working directory differs from what the user expected, or when Windows/Linux path separators are mixed.
