I would suggest you stick to the latest stable release unless you need a specific fix from the beta or have a working system and want to do some testing.
It looks like your DWC version is out of sync with your firmware version.
To get back on track I suggest you upload this zip file to the system tab in DWC.
https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.5/Duet2and3Firmware-3.4.5.zip
Then check your versions afterwards to see if they match at 3.4.5

For the PanelDue, see here: https://docs.duet3d.com/en/User_manual/RepRapFirmware/Updating_PanelDue
You'll need to identify your paneldue version and get the correct firmware file for it.
