Error message (Unexpected exception when initializing view part ...fragments)

Hi there,

For about 2 weeks now I have been getting the enclosed error message when trying to open any file for translation/editing. Trados lets me create new projects and pre-translate files without problems; then it shows the error message when trying to open these files. I am not sure whether it is related to updating to the new release (that happaned roughly at the same time) or to updating a new version of DeepL Translation Provider (which also happaned roughly at the same time) or whether it is completely unrelated.I have uninstalled and reinstalled Trados completely, but the problem remains exactly the same.

Everything works fine on my laptop, where I haven't upgraded to the latest version, though.

Thank you for any tips as to what the problem might be and how to solve it.

Many thanks, Holger
