1.  if used the Premiere pro exporter GUI (File->Export->Media...) and imported the same preset file (export_1080p_H265.epr) , encoding was successful 
2.  Tried to create and save a new H256 preset file from Premiere Pro v25.3.0, the code still not worked
3.  the code was working for H264 preset file

var out_put_path = "C:\\Temp\\adobe_premiere\\out_put.mp4";
//var preset_path = "C:\\Temp\\adobe_premiere\\export_1080p_H264.epr";
var preset_path = "C:\\Temp\\adobe_premiere\\export_1080p_H265.epr";
seq = app.project.activeSequence;
if (!seq)
{
    alert("No active sequence found. Please open a sequence in the project.");

@Harishpal301676443nmz  this error is caused by a change to Premiere Pro that was added in v25.3. It is no longer possible to programatically export HEVC. This was an intentional change. The change does not affect any other codec options.
