Hi @Orkun Oran ,
According to your description, this is an occasional problem. Don't worry, let's do some simple troubleshooting to further narrow down the problem:
- Try to switch the browser or open the browser privacy mode.
- Try to open the file through the client.
- Try to download the file locally and open it with the client.
- Try to check the version history of the file to see if the file was damaged due to some problems before. If the previous version can be opened, you can choose restore to restore the previous version to the current version.
- Give another account permission to see if it can be opened.
