Windows my save file disappeared

[maddy_loves_elliott]

the save still exists, but my game won't load it. I use SMAPI, this is what it says:

[game] Exception occured trying to access file 'C:\Users\DELL\AppData\Roaming\StardewValley\Saves\Pinewood_284512023\SaveGameInfo'

[game] System.Xml.XmlException: Root element is missing.

at System.Xml.XmlTextReaderImpl.Throw(Exception e)

at System.Xml.XmlTextReaderImpl.ParseDocumentContent()

at System.Xml.XmlTextReaderImpl.Read()

at System.Xml.XmlTextReader.Read()

at System.Xml.XmlReader.MoveToContent()

at Microsoft.Xml.Serialization.GeneratedAssembly.XmlSerializationReaderFarmer.Read119_Farmer()

im pretty sure the save file is not corrupted, rather it's an issue with the game itself, because this happened with other saves too. i tried using the backup save too, still the same. someone help!
