Save your RDP connection, ie 'HomePC.rdp'
Right click and edit in Notepad
Add the bottom add these 2 lines:
enablecredsspsupport:i:0
authentication level:i:2
Save file and attempt to RDP again, it should skip passwordless auth, which I don't believe is supported for traditional RDP and you can just enter your password into the login prompt. Its what I do to connect to some AAD machines, I have.
