Error in loading the data

Hi,

I am trying to load data but getting an error
My query: call apoc.import.graphml("C:\Users\lajja gupta.Neo4jDesktop\neo4jDatabases\database-fe88e297-6e1c-488f-b34c-fb809228a509\installation-3.5.6",{batchSize:10000,storeNodeIds: false, readLabels: true})

error message: Neo.ClientError.Statement.SyntaxError: Invalid input 's': expected four hexadecimal digits specifying a unicode character (line 1, column 31 (offset: 30))

What should I do to load the data?
Thanks in advance
