Erro esperado de literal de token no código M do Power Query usando try e List.MatchesAny

Estou trabalhando em um script do Power Query M para renomear colunas em uma tabela com base em certas condições. No entanto, estou encontrando um erro "Token Literal Expected" ao tentar usar a tryexpressão dentro de uma List.MatchesAnyfunção. Aqui está a parte relevante do meu código:

RenameColumnsFunction = (table as table) as table => 

let ColumnNames = Table.ColumnNames(table),

//Apply transformation logic to each column name
RenamedColumns = List.Transform(ColumnNames, (colName) =>

// If any column values have a length of 4 and are numeric, rename the column to "Org level 2 Code"


    if 
        List.MatchesAny(Table.Column(table, colName), each try 
        Text.Length(Text.From(_)) = 4 and **try **
        Number.FromText(Text.From(_)) <> null otherwise false) 
        then
        {colName, "Org Level 2 Code"} 

// If the column name matches one of the predefined names, rename it to "Headcount Label"
        
        else if 

        List.Contains({"ACCTG", "ADMIN", "ASM", "AWE", "CFO", "CROCOL", "CUSTSRV", "DEV", "ENGIN","FIN","FLDSP", "HOM", "HR","IT", "MERCH", "PROSVC"}, colName) 
        
        then
        {colName, "Headcount Label"} 
        
        else {colName, colName}  // Keep the original name if no match 
        
        ),
        RenamedTable = Table.RenameColumns(table, RenamedColumns, MissingField.Ignore) 
        
        in RenamedTable, 

// Step 4: Apply the renaming function to each table query
ApplyRename = Table.AddColumn(FilteredQueries, "Transformed Data", each RenameColumnsFunction([Content])), 

// Step 5: Expand the renamed tables (ensure there's data to extract) 
RenamedTables = Table.ExpandTableColumn(ApplyRename, "Transformed Data", Table.ColumnNames(ApplyRename[Content]{0})),

// Step 6: Combine all queries into one table if needed 
CombinedData = Table.Combine(RenamedTables[TransformedData]) 
in
