It’s possible that the error is caused by the file path being too long. The maximum length for a file path in Windows is 260 characters, and if the file path for the Excel file you’re trying to open exceeds this limit, you may encounter this error.
Another possible reason for this error is that the file is corrupted or being used by another process, but the file path being too long is the most likely cause. You can try moving the file to a different location with a shorter file path to see if that fixes the issue.
