{KIndle Fire] Cailibre shutting down

[MIKEG123]

Hi all
Apologies for almost certainly posting this in the wrong place but I simply cannot find the correct place. Please feel free to move the question to where it should be.
I bought a new Kindle 8 today, I already have a 7 inch fire.. My calibre running in Windows 10 shuts down as soon as I instruct the Fire to exchange files. I have tried everything I can see and downloaded the latest version of Calibre. Error log below. Any help would be greatly appreciated as I'm out of my depth. Thanks in advance.

Sadly this happens with a few MTP devices, I have never been able to reproduce so cannit fix. You cna try either restting the Fire or use one of the wireless methods described in: https://manual.calibre-ebook.com/faq...kindle-fire-hd
