I actually just ran into this backtrace myself.
The cause is due to changes made in scala-xml 2.2.0, which based on the
backtrace looks like is what you are using. We have a pull request to
upgrade scala-xml to 2.2.0 in Daffodil and fix this, but it is still
waiting on another review:
https://github.com/apache/daffodil/pull/1060
However, that should not affect Daffodil 3.5.0 since it still depends on
scala-xml 2.1.0, which does not have this problem as far as I know. Have
you manually upgraded to 2.2.0 yourself? I think downgrading scala-xml
should fix this for you.

Hello – In attempting to upgrade from Daffodil 3.3.0 to 3.5.0 I’m
running into the issue that compilation of any DFDL schema causes the
exception below. What could cause this?
Example code:
public void compile( String schema ) throws IOException
{
Compiler compiler = Daffodil.compiler( );
ProcessorFactory pf = compiler.compileFile( new File( schema ) );
if ( pf.isError( ) )
{
System.err.println( "Failed to load schema: " + schema + ", " +
asString( pf.getDiagnostics( ) ) );
}
}
