Rich text editor not visible in back office after upgrading from U10 to U13

We have upgrade our application from Umbraco 10 to 13 and notice, RTE is not visible in back office. But it’s content is working fine in front end application. Kindly suggest how to fix it?
The image shows a user interface with text fields labeled "Left Side Text" and "Right Side Text", and buttons for "Save and preview", "Save", and "Save and publish". (Captioned by AI)

Are you sure it’s not browser cache? Open your development toolbar and select ‘no cache’ just to make sure.

Hi @LuukPeters , Yes I tried but still getting same issue. Also, Just wanted to let you know we are using Umbraco version 13.7.0

Hi @LuukPeters ,

Thank you for your response.

Issue resolved, actually umbraco.directives.min.js file was not loaded correctly. It was pointing to old version(v 10.6.1).
