Error message

补丁安装失败，原因：文件修改器初始化失败！

What it means

AppModifier.Patch() throws a plain Exception if any element of the editors list is null. In the normal flow InitEditors only adds non-null FileHexEditor instances, so a null implies the list was externally mutated or a subclass/test injected a null.

Solutions

1. Do not mutate the editors list after InitEditors.
2. If subclassing AppModifier, ensure every editor added is non-null.
3. Filter nulls out of editors before calling Patch().

if (editors == null || editors.Any(e => e == null))
{
    throw new InvalidOperationException("editors 列表包含 null，请检查初始化逻辑。");
}
if (editors.Count == 0)
{
    throw new Exception("补丁安装失败，原因：无对应的文件修改器");
}

When it happens

Trigger: The editors list contains a null entry when Patch() runs. Not reachable through the public API if InitEditors is the only thing populating editors.

Common situations: Subclass or integration code replaced editors with a list containing null; a failed FileHexEditor constructor result was added manually.
