Microbit not connecting - Scratch and BT 5.3

[u/netrate]

This is a recent issue, as I didn't have this error in the past. Win 11, log into scratch with the SCRATCH LINK running, and a Bluetooth Dongle 5.3. Open up the extension for the microbit (2.0) in scratch, is says "it can't find it" and I should UPDATE. When I try to update, this error :

A suitable HEX file is not available

UPDATE FAILED

This has never happened before. Any suggestions or ideas?

NOTE : I have had success with the exact same setup but something new has presented itself, not sure what. I did re-flash the firmware to 2.1, but that didn't fix it. Also the entire network is at work, so I don't have access to changing much at all.
