main.CRITICAL: Error: Call to a member function create() on null in
/public_html/vendor/magento/module-catalog/Model/Category/DataProvider.php:663

Can anyone suggest a solution?

Hi @usercm,

Find the find by entering this path: 

/public_html/vendor/magento/module-catalog/Model/Category/DataProvider.php 

After that, find line 663 and replace: 

Converted into

$config = $this->uiConfigFactory
            ->create(['componentName' => 'category_form'])
            ->get($referenceName);

Hope this can help you! Let me know if you need further assistance.
