PSDC file wont stop Syncing

It would be good if we could get a copy of the file from this location: C:\Users\<your username>\AppData\Roaming\Adobe\CoreSync\cloudnative\DCX\3758150cef8e68fad92d0e4bc3f8b46a\1/v1/blob/2c1/2c1844fe-9282-4708-95d0-4bfb33f6dbfd.png

1. Logout from Creative Cloud. Photoshop should also get logout but just check if its logged-out & close it, if not already closed.
2. Just check if CreativeCloud, AdobeDesktopService, CoreSync processes are running in Task Manager. If yes, please kill them.

3. Just ensure to have Internet Connectivity before working on any of the steps below.
3. Login to Creative Cloud application first.

After you have given your consent to collect the logs, the Log Collector tool collects the required files from your computer and saves them as a ZXP file on your desktop. Click Upload (Windows) or Continue (macOS) to share the log files with Adobe

I ran the log collector, do I have to upload the files somehow? or does it automatically get sent over. Apologies, I'm new to all this. 

Could you please run the log collector tool and submit your logs so I can have an engineer take a look? Instructions here: https://helpx.adobe.com/creative-cloud/kb/cc-log-collector.html
