Can you share the source file so we can test it?  Even make up the source file (it looks short) and add in the appropriate images to you can reproduce the issue.

How can I upload an sdlxliff file? I get the message : File type is not allowed. I tried  Insert > image/video/file and upload

This is the german source file. But I can't upload the sdlxfiff

As I encountered the same problem yesterday, you can find the new Word file and the corresponding sdlxliff file from the previous translation plus the sdlxliff file with Perfect Match applied for the new Word file in the location well known to you. I have got exactly the same error message as Ute.

You can zip the sdlxliff file and upload then. This works.

PerfectMatchTest.zip

Thank you!

These are the files from the directory in the target language. 

PerfectMatchTestDE.zip

An these are the files from the source language

Hi Paul, did you notice that I uploaded two zip files? The problem still exists.

Are you perfect matching with a file created in a different version? I ask because I took a small part of your source file to test quickly and doing it all in 2022 SR1 my perfect matched file looks like this and has no problems at all:

So... I tested again with your full file.  This time, interestingly I get the same result as you:

So I tried again, this time with only the segments in the error... no issues at all!

So a bit tricky and needs more time to investigate than I have!  The word file itself is problematic for me and keeps hanging my computer and it's difficult to edit, but nonetheless I think we need to get to the bottom of the problem.

Presumably you don't have this problem with all the files you work with?

I have been working with SDL Trados Studio 2017, 2019 and also 2022 for several years. I have had the problems exactly since I updated SDL Trados Studio 2022 to 2022-17.06.14902.
Unfortunately I have the problems with all files, because I use a lot of picture tags. Therefore, Studio has not been usable for me for several weeks.
Your first test does not contain a picture tag, so the error does not occur there. The first picture tag is in segment 11.
Unfortunately, I can't tell you exactly which constellations lead to the error. I was very happy to have a small example that you can use to reproduce the behaviour.

In my case the files have been all processed in S2022. However, the source file for PM was pre SR1, while the translation has been done with SR1. Nonetheless, as Ute says, such problems did not appear before.
