RDP from linux to windows
You can try to change security settings of connection from "negotiate" to "TLS" in Remmina or you can try VNC connect
FreeRDP introduced support for the new NLA versions in the v2.0.0-rc2 ( https://github.com/FreeRDP/FreeRDP/pull/4499/commits/8df96364f2d556d3dc34241de27fdb89c0d5bb42 )
It looks like Remmina also updated its FreeRDP library ( https://gitlab.com/Remmina/Remmina/issues/1513 )
So depending on your distro it might be fixed by updating your packages. Otherwise you can always compile Remmina from source yourself.
