Dear Margarida Vaz,
Welcome to Microsoft Community.
We understand that you want to recover your unsaved PowerPoint file.
According to your description, your file was created, saved, and viewed on a tablet. We need to confirm with you:
Did you save the file in OneDrive? Or in other ways?
Usually, if you use the PowerPoint program on a tablet, the file may be saved in OneDrive. You can try to confirm whether you can view and recover the corresponding file through OneDrive.
If you save it in other paths on the tablet, this needs to be further confirmed through your device.
- Log in to the OneDrive web:
You can try to log in to the OneDrive web page: https://onedrive.live.com/ to see if the web page can view your synchronization information and the new file information after your operation.
If yes, you can try to download your file through the web page, and then reopen it to confirm.
2. Use OneDrive's full search:
You can try to enter your folder or individual file name at the top of the web page, and after searching, reopen the document to confirm the information.
3. Check the OneDrive Recycle Bin:
You can click the OneDrive Recycle Bin option to confirm whether your project exists through the Recycle Bin.
If yes, you can try to click "Restore" to help confirm the information.
You can use the following links to find out more information about your files:

If you have a Microsoft 365 subscription, you can use the Restore OneDrive feature to help you restore and find previous versions of files in OneDrive.
Restore your OneDrive - Microsoft Support
If you still cannot restore your files, in order to further help you find the file information, we recommend that you try to send an email to the OneDrive technical support team through the following link to provide feedback. We can help you check the file status under your account. https://onedrive.live.com/?action=feedback
