isabelle cottenet I think we'll need support to look at this if you've tried these things already, and maybe also uninstalled and reinstalled. So I have logged a support case on your behalf. You will be contacted at the email address used for this Community. Support Case Id : 00657138 .

Thank you Paul. I hope they'll be able to help me and figure out what is happening. I've been using Trados for... ages (since 2002), and this is the first time this happens!

Hi, I had a remote session with Trados support who was able to provide me with a workaround: The problem occured at the project creation. I had created the project "the old way" (could this be the reason?). The workaround : Open Studio 2021, click on the "Home" tab, drag and drop the file to translate and select either "Create New project" or "Translate as a unique document" (Traduire en tant que document unique). For the moment, Trados no longer crashes or displays the error message. Thank you Paul and Catalin :-)

I had the same problem in Trados 2021 with a project sent to me by an outsourcer. He created a package in order to solve the issue, but it did not solve it.

I was able to open and translate the same "corrupted" source file in Trados Studio 2017 without any problem... Sooooo. What use is it to me having a brand new software performing less well than its previous version???
