Fehlercode 47 - mehrfache Dateien betroffen

Hi @David31425751y7a3, although I'm not familiar with the error, if you haven't tried all the suggestions mentioned by @Atul_Saini in this conversation, (although your file is local, some suggestions still apply) I'd suggest trying them:

Hey everyone,

Sorry to hear that you're unable to open the file and get an error "Sorry that you are unable to open this document." or  Error 47, unable to open the document." We'll try our best to help you with this. 

First, there are two quick solutions which you may try. 

1. Open the same file on a different machine or user account( Windows 10/ Mac). 
2. Download a previous version of the file from version history from assets.adobe.com using these steps (https://community.adobe.com/t5/adobe-xd/revision-history-in-xd-helps-ensure-peace-of-mind-during-col...).

If the problem still persists, please try the following suggestions. 

Step 1. Ensure that XD is up to date using this link (https://helpx.adobe.com/in/creative-cloud/help/creative-cloud-updates.html).

Step 2. Follow the instructions mentioned on this page step by step (https://helpx.adobe.com/xd/kb/fix-issues-with-xd-cloud-documents.html#unable-to-create-open-cloud-do...). Before proceeding to the next step. Please upload the logs to CC or Dropbox and share the link with me via PM (click on my name and hit the message button on my profile). This would help us to get to the root cause and investigate further. 

Step 3. Please try cleaning the Creative Cloud desktop app from the cleaner tool: https://helpx.adobe.com/in/creative-cloud/kb/cc-cleaner-tool-installation-problems.html and then reinstall the Creative Cloud desktop app from here (https://helpx.adobe.com/in/download-install/kb/creative-cloud-desktop-app-download.html).

Please share logs with Harshika Verma so that we can escalate the issue to our team for further investigation

Thanks,

Hope this helps!
