That result suggests that something changed about your windows settings between when it was working and when you tested yesterday.
My googling suggests that the Nadja DAC is a PCM only device that supports up to 192kHz, but that the WaveIO might be reporting a wider set of capabilities.
I don’t think this relates to the “force max volume…” setting, since it doesn’t seem that your WaveIO+Nadja combination supports DoP, and that is a DoP specific problem.
Try setting your max sample rate (in Roon’s device settings) to 192kHz and combining that with the “none” DSD mode on the SOtM.
