Regardless the source, such error is caused by merging segments across paragraph breaks. One of the paragraphs has contained an image before merging. After the merging the image/illustration is moved to another paragraph. Usually you could see that due to new tags appearing in such merged paragraph.

When merging segments across paragraph breaks you always should try to generate a target file immediately after merging to make sure this works. And you should also try to open such target file in Word immediately - because even if target will be created it is also possible, that Word will not open it anymore.

Hi Jerzy – thanks for the correct diagnosis, found your comment useful when searching for this. Just to check – is there no way, as far as you know, of undoing the incriminating merge? For example by dividing the segments again?

Thank you!

I am not moaning, be careful with your language...

There is nothing intuitively indicating that I should do this. So, please be respectful a bit or dont write to my questions. 

I am quite respectful. And the fact you have to switch to the target language is known since adding files to a project is possible. It is not my fault, that you do not know the basic, but still post things like "So, the regular trados shortcut: create the entire thing again"–this is what I call moaning.

Sir, use that kind of language to the female family or relatives, Or your mother... not to people who just wasted 20 minutes here 10 minutes there to convince the software. You and I are never going to agree, so dont cross basic lines of respect. It cost me 30 minutes that is why I am frustrated, if it was intuitively available, I would have done it. I wont waste my time explaining like before. so, watch your language!

It is intuitively available, when using "Quick add files", which is present since at least Studio 2019.

If you don't know the very basics, but blame the software for your missing knowledge, you cannot mind an expert who gradually gets annoyed about such ignorance to keep the velvet gloves on! And Jerzy only said "moaning", HE DIDN'T INSULT YOU, you should be able to tolerate this and try to learn!

You instead shut up. We have a history and not a good one but always respectful until today. You wrote "shut up" end edited. Hush! you! I dont have time to waste like this. Shut up as you said. 

Seriously, stop writing please.

What do you mean with "a history and not a good one? Are you getting political, bah! Trying to discuss with someone like you is forlorn hope.

It is not political, we had some arguments with him yesterday and it was rather respectful. That is the history. Nothing political. This is not the place for that if I were to do that. Thanks.

I'm closing this thread.  The original post has already been answered and I don't think the conversation now is helpful.  Please remember that this forum is intended to be a helpful place for all users, so when you ask questions please try to provide as much information as possible about the problem and try to stick to the point.

If you are kind enough to reply and offer some advice then similarly try to avoid personal comments and stick to the point.  It can be tricky working in a forum with so many different cultures and levels of knowledge, but if we all remember that everyone either needs help or is trying to help then I think it's a great place to discuss things without any moderation needed.
