I haven’t tried it, but based on what you are doing, it may be something is getting too hot. Make sure it’s ventilated.
There have bee a number of small compute intense boxes over the years I’ve owned which malfunctioned due to the manufacturer not taking care to ventilate and add appropriate heat sinks. These were usually wifi routers but also indludes Roon like streamers. Additional cooling often helped.
My Mytek DAC also suffers this if fed very high sample rate music, so I put pucks underneath it and limit the signal rate.
With the wifi routers I sometimes would drill a hole over an offending chip and add a heat sink and micro fan. Not saying you need to, just saying it’s happened so often that I’m kind of surprised it doesn’t happen now.
I'd feel the dac and look for any particularly hot areas above or below and take care that any hot areas get extra ventilation.
