And i have no idea why it comes. I tought it was because of the update as then it takes the newest ones and so. But even with the install i get this.

Composer.json

        ]
    },
    "config": {
        "preferred-install": "dist"
    }
}

The only thing i can not do is use the php 5.6 as my service provider does not go that low. The oldest one i can use is 7.0

Add the composer.json file to your question to check if there's any problem with it — Daniela C. Montenegro, Feb 10 '21 at 13:16
There's a good reason you should not run `composer update` if not needed :) — Nico Haase, Feb 10 '21 at 13:55
@user1709407 , why are you running `composer update` in the first place?. Are your trying to upgrade your Laravel version?. Which command did you run exactly?. Since both `composer update` and `composer install` serve different purposes. — steven7mwesigwa, Feb 12 '21 at 16:36

I've compared your composer.json file with the official 'JSON' file for your Laravel version and it appears to be in good shape. Original Laravel v5.3.* composer.json file
Please only run composer update if you have to. Learn about the difference between composer update and composer install from here. What are the differences between composer update and composer install?
From your 'error log' it's complaining about a missing class Class 'Doctrine\Inflector\InflectorFactory' not found in Inflector.php line 70.

The file in question resides at testProject\vendor\doctrine\inflector\lib\Doctrine\Common\Inflector\Inflector.php. 'testProject' is my project name while trying to reproduce the problem.
Normally, this can easily be fixed by simply adding an import statement for the missing 'Class' which in my test case already exists. i.e use Doctrine\Inflector\InflectorFactory;
Original Inflector.php file in a fresh installation.

❌Since its generally bad practice to manually edit files in the vendor folder that reside in your project root directory, below is my suggestion.

Procedure

Delete your composer.lock file from your project root directory.
Delete the whole vendor folder from your project root directory.
Open your terminal/PowerShell, ➡ navigate to your project root directory, ➡ run the command composer clear-cache
This will delete all content from Composer's cache directories.
Open your terminal/PowerShell, ➡ navigate to your project root directory, ➡ run the command composer update
Wait for 'composer' to write a new lock file and to install the fresh dependencies.
Make sure the file app/helper.php exists since I saw it in your customized composer.json file.
I had to remove that declaration below from the customized composer.json file since I didn't have access to the app/helper.php file while testing.

// ...
,
    "files": [
        "app/helper.php"
       ]
// ...

If the 'update' is successful, all should be well.
In your project root directory, you can run the command php artian serve and navigate to the displayed output URL in your browser to confirm if the error has disappeared.
