Trying to add a new term onto my termbase currently open on Trados Studio is not possible, an error message appears

Hello, I have just updated my Trados Studio 2019 as I started using Windows 11 and my Studio went to be unable to create a project. I could open a single document only for translation. That problem has been solved by downloading a cumulative update for Trados Studio 2019, but I cannot add a new term from the document open on my Studio editor though I have highlighted both source and target terms, and the "add new term" button is not grayed-out. It shows an error message "Object reference not set to an instance of an object". I tried "quick-add" but the result was the same error message. Please help. I have seen similar posts but not a solution.

    "Question improvement suggestion": Please provide the exact steps you took before encountering the error, and any troubleshooting steps you've already tried. Also, please confirm if you've made any recent changes to your system or software.

    In the meantime, based on the information you have provided, here is a suggested answer to your question:

    Hello,

    It seems like you're encountering a known issue with Trados Studio 2019 on Windows 11. The error message "Object reference not set to an instance of an object" typically appears when there's a null reference, meaning the software is trying to access a reference that doesn't exist.

    Here are some steps you can try:

    Step 1: Ensure that your Trados Studio 2019 is up-to-date. You can check for updates within the application.

    Step 2: Try to restart Trados Studio. Sometimes, a simple restart can resolve the issue.

    Step 3: If the issue persists, you can try to repair your installation of Trados Studio. To do this, go to Control Panel > Programs > Programs and Features, select Trados Studio 2019, and click on Repair.

    Step 4: If the error still occurs, you might want to consider reinstalling Trados Studio 2019. Please make sure to back up your settings and projects before doing so.

    Step 5: As a workaround, you can try clicking on any of the existing terms in the cloud termbase and then try again to add the new term. This has been suggested as a temporary solution to the issue.

    Please note that this is a known issue and has been logged with our Development team for further investigation. We appreciate your patience and understanding while we work on a permanent fix.

    I hope this answer addressed your question. If not, please reject the answer, add the question improvement suggestion information, and click the RWS Community AI checkbox on the right to try again.

  • My Studio 2019 is up-to-date and my problem is adding a new term onto my termbase (multiterm 2019, which is also up-to-date).

    It shows an error message "Object reference not set to an instance of an object"

    Please can you click on the small disk symbol at the bottom of that error message, and then attach the file you save from that to your reply.  The error message is a very bland message that could be caused by all sorts of problems.  The error message might help.

    Also, please check that your termbase is not on a path that contains OneDrive because this could be one cause of this issue since the termbase might actually only be a placeholder since the actual termbase i in the OneDrive Cloud.  In this case Trados Studio won't be able to use it.

  • Hello again Paul, this is the only way I have been able to upload the error file I saved yesterday, but I am not sure if you can receive it OK on your end. Thank you so much again for your help.

    Thanks for sharing the error stack.  I think this is most likely the key: <Type>System.NullReferenceException

    An error like this can occur if you are using OneDrive and have stored the termbase on a path that is part of a OneDrive location.  For example:

    c:\Users\[USENAME]\OneDrive\Documents\Studio 2024\Termbases\my.sdltb

    If this is the case try copying the SDLTB to a location that is not on a path with OneDrive in it and see if this resolves the issue.

  • C:\Users\[USERNAME]\Documents\Studio 2019\Termbases\xxxxx.sdltb

    The above is the path of the termbase I am using, and the last entry was a month ago, so this is the most current one. However, I have updated my system to Windows 11 recently, and the termbase cannot have new terms added since then. I would appreciate your help here. I am not a OneDrive user either.

  • Hello again Paul, I have now opened my Multiterm 2019 and tried to open my termbases. Then it shows this error message, which I believe is related to my first problem. Please see the screen capture of the error message on my Multiterm 2019.

  • This is my 3rd error message with regards to my Multiterm 2019 so far... I couldn't open my most current termbase from my local folder, which is shown in my previous message, so I have tried to create a new termbase. This time, my local folder with all the other termbases were visible, so I tried to save a new termbase with a new name, then this error message appeared, and I don't have a disk icon on this error message... I would really appreciate your help here...Screenshot of Trados Studio with an error dialog box stating 'Object reference not set to an instance of an object.'
