php artisan route:list is emitting every single route correctly. I haven't changed anything in config, project etc.

Let me check.

Can you please let me know your PHP version as well?
Probably need to add a condition such as below:

You can try it updating inside the vendor and see if it works for you on Line 126.

C:\Users\****\****\vendor\rakutentech\laravel-request-docs\src\LaravelRequestDocs.php:126

           // on line 126
            if (class_exists(ReflectionUnionType::class)
                && $paramType instanceof ReflectionUnionType) {
                $requestClassName = $param->getName();
            } else {
               $requestClassName = $param->getType()->getName();
            }

@kevincobain2000 It's not working. PHP is 8.1.
After adding you code with condition "class_exists(ReflectionUnionType::class) && $paramType instanceof ReflectionUnionType" a got the same error.

In LaravelRequestDocs.php line 130:
Call to undefined method ReflectionUnionType::getName()

But this works fine:

            if (class_exists(ReflectionUnionType::class)
                && $paramType instanceof ReflectionUnionType) {
                $requestClassName = $param->getName();
            } else {
               $requestClassName = $param->name;
            }
