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.

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.
