Hello, Sophie.
Welcome to Microsoft Community.
I'm sorry to hear that you're experiencing issues with opening your PowerPoint file. This problem may be due to file corruption. Here are a few workarounds you can try to resolve this issue:
- Make a copy of the original file and try to open the copy.
- Try opening the file on a different computer to see if the issue is specific to your current device.
- If you have a backup of the file, try opening the backup copy.
- You can also try to repair the PowerPoint file by following these steps:
- Open PowerPoint.
- Go to File > Open.
- Browse to the location of the file, select the file, and click on the arrow next to the Open button.
- Choose "Open and Repair" from the drop-down menu.
If none of these steps work, please let me know, and we can explore other options to help you recover your presentation
Best regards,
Oscar Calvo
