After installing update KB5002373 (database version 16.0.10397.20002), SharePoint 2019, on premise, gives following error when trying to open a list:

Cannot make a cache safe URL for "next/odspnext/en-us/splistreactcontrolsbeforeplt.resx.js", file not found. Please verify that the file exists under the layouts directory.

Re-run Configuration wizards without success.

    Hi @Margine, David,

    Thanks for posting in the community.

    In the installation steps you need to run Configuration wizards on Central Administration server, Application server and web server.

    Check installation process in this article: Install a software update for SharePoint Server - SharePoint Server | Microsoft Learn

    In the question, you describe that rerunning Configuration wizards did not success, which server are you running Configuration wizards on and did Configuration wizards succeed when you first installed the update?

    If you can, please re-run the Configuration wizards and send me the ULS Logs, which will help me better find the cause of the problem. Be careful to code your private information in the logs.

    Before you re-run the Configuration wizards, I recommend that you do a full backup of your SharePoint Server,

    Here is the article about backup solutions for SharePoint Server: Backup solutions in SharePoint Server

    Here is the method to get the real-time ULS Logs when you reproduce the error:

    1.You can download the ULS Viewer from the Microsoft Download Center.

    2.Open the ULS Viewer on a SharePoint server and hit the play button on the top next to the open button. Or just hit CTRL +U.

    A screenshot of a computer Description automatically generated

    When you have finally found your error, click on the column to view detail messages. You can copy the Log message to me and that is what I need.

    Hi Ling,

    After searching the net and reviewing the logs I found that installing the latest Language Pack fixes this issue. The problem was that the file splistreactcontrolsbeforeplt.resx.js was not found in the folder C:\Program Files\Common Files\microsoft shared\Web Server Extensions\16\TEMPLATE\LAYOUTS\Next\odspnext\en-us. The language pack seems to have solved this problem.User's image

    Thank you.
