we used E5 licences and the windows version is windows 11 23H2

I have tried many things but still encounter the error up to now.

I attempted to repair the Office installation and connected with a user outside my organization.

I also tried turning off and on the optional connected experiences feature. Additionally, I attempted to add the DNS 4.2.2.1 and finally disable Defender on windows machine . Do you have any ideas? Please advise."

Hi @ APTOS ,

Judging from the screenshot you provided, the problem seems to occur in Word. When you try to translate the document, an error occurs.

Does the same error appear when you select partial translation? If it works fine, according to my search, the issue could be due to the document extension, it is recommended that you save the document as a docx file and then translate it.

Hi @ APTOS

If you open the documents from Word for web, does this issue persist?

1 If yes, maybe the internet connection or other settings related to network cause this issue.

Please disable the VPN or proxy connection if there is.

Please also ensure the Microsoft 365 URLs are not blocked.

2 If not, it may be some reasons of Word app. Please go to File > Account > Product Information, check the update channel and version number.

I suggest you close all Office apps, go to Registry Editor, locate to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\WEF\SolutionPackages , remove it. (Serious problems might occur if you modify the registry incorrectly. Before you modify it, please remember to back up the registry for restoration in case problems occur.)

Hi @ APTOS

Thanks for your feedback.

If the registry key does not exist, please try to back up the registry key, and delete it: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\ExperimentConfigs

If the issue persists, I suggest you create a new local Windows administrator account, find the Word program to open and check this issue.
