ODBC MSSQL Fetch Type out of range

Databases
1

Using Windows 10 and Xojo 2023r2 on Web
MSSQL connecting using ODBC 64 bit with SQL Server driver
When I use a select statement with parameters, I get an error “Fetch type out of range” on the SelectSQL line. If I remove the parameter then it works without error.

var sql as string
var rs as rowset
sql = "Select email FROM admins WHERE region = ?"
try
  rs = Session.db.SelectSQL(sql, PmBranch.RowTagAt(pmbranch.SelectedRowIndex).StringValue)
catch e as DatabaseException
  messagebox(e.message)
end try

if rs <> Nil then
  if not rs.AfterLastRow then
    FinalEmail = rs.column("Email").StringValue
  end if
  rs.close
end if

Windows uses “WideChars” AKA UTF-16 by deafult, Xojo uses UTF-8, I guess something may be being lost in the translation.
