Laravel项目服务器端提交含格式/图片的表单报405错误求助

本地环境一切正常，但在服务器上提交表单时，只要在文本编辑器中使用text-align对齐或插入图片，就会返回405 Method Not Allowed错误。

已尝试的解决方案 #

• 将路由改为match/any方法：不再返回405，但提交的payload为空
• 通过Ajax请求提交表单
• 调整中间件配置
• 通过.htaccess禁用ModSecurity
• 更换TinyMCE/CKEDITOR等多款富文本编辑器
  以上操作均未解决问题。

路由配置 #

Route::get('/dashboard/new-project', 'BackofficeController@getNewProject')->name('backoffice.new-project');

Route::post('/dashboard/projects', 'BackofficeController@createNewProject')->name('process.create.new.project');

控制器代码 #

public function getNewProject()

    $project_type = Project_type::all();

    $products = Product::with([
            'sub_category' => function ($query) {

即使直接通过Laravel原生表单提交，也会出现相同问题，恳请帮忙解决。
