You diagram is not BPMN 2.0. It starts with

<?xml version="1.0" encoding="utf-8"?>
<BPMN BPMNVersion="1.9">
  <BusinessProcessDiagram id="(f9c6d725-d570-4adf-80b3-2a8ca9444eaf)">
    <Name>New BPMN Model</Name>
    <Description />
    <IPCode>IP-010</IPCode>
    <Version />
    <Author />
    <CreationDate>637513936242199875</CreationDate>
    <IsCopyFromTemplate>false</IsCopyFromTemplate>

I’m curious. How and when was this diagram created?
