I have the same bitcrusher effect with the Babyface Pro on Windows 10 with latest firmware/drivers and TotalMix 1.75. This happens on my DeskMini X300 system (https://www.asrock.com/nettop/AMD/DeskM … /index.asp) with a Ryzen 5600G APU.
The Babyface Pro is connected to the only external native USB 2.0 port, but there are an additional 2 USB 2.0 ports from a bracket connected to the only 2.0 internal 9pin header.
When the BabyfaceP is the only USB2.0 device connected, or when only a USB2 keyboard is also connected, audio is flawless at the lowest latency @ 44.1k. However as soon as I plug in another USB 2.0 device into the header bracket (tested with a couple of pen drives), while the device is being accessed, the bitcrushing kicks in, gets worse over a few seconds to where the (crushed) audio then gradually fades out, until it's completely silent - either permanently (until ASIO playback is stopped and restarted), or sometimes it briefly comes back before crushing out again. This happens even at high ASIO buffer sizes - it's like the other devices unfairly hog the 2.0 bandwidth and choke the ASIO stream (educated guess), or maybe they affect transfer timing somehow?
I know that AMD has had overload issues with their Ryzen USB controllers, and those have been patched in various BIOSes. Is this a remaining side effect?
Happy to try anything - is the debug driver still valuable, or too out-of-date?
Seems that your system has no PCIe expansion slots. Then it would have been possible to add an dedicated USB3 PCIe card to your system to isolate the recording interface from the rest of your systems USB infrastructure. As nice as it is to have a very compact system. If it's too small then you can e.g. not expand like in this case to get a potentially better solution than having to wait for BIOS updates, where you never know, whether a) it can be fixed in the current chipset and b) this fix is still intact in further (potentially required) upgrades.
My server mainboard has a good Intel Chipset C612 and I could initially connect two UFX+ (with a lot of audio channels!!) and an ADI-2 Pro. Issues arised once I started connecting additional USB devices for Bluetooth and additional stuff, then I got audio drops at lowest ASIO buffersizes, which were not there before.
I could fix that by adding an USB card with supported FL1100 USB3 controllers. In this case an expensive card, because it had four USB3 controller on board, so that each connected device can be fully isolated behind such an USB3 controller and also has the full USB3 bandwidth.
If you look for such a card then I check that it also has support for UASP, because this enables for faster and more efficient data transfers, which is very interesting to be able to provide fast backups and restores and especially if you have to deal with a lot of small files. An external USB based backup device you can turn off as long as you use a recording interface. Then you can take a good card to a more affordable price, where 1-2 USB3 controller are shared for four USB connectors.
Sonnet builds good card, but also Startech has good offerings and has also matching USB housings which also need to support UASP if you want to make use of this technology.

I tell you this so that you have a chance to draw a good decision, whether to stay with this small system or to make some thoughts how to expand. Typicall you could keep CPU and cooler (would get a good and silent tower cooler instead), DRAM and then get a case with good PSU (e.g. hybrid where blower only turn on when needed under load) and generally a better mainboard, but look that you get a supported one for your CPU and with e.g. passive cooling for the chipset and the features that you need. The board needs to provide connectors for monitors if you want to keep using your CPUs internal GPU. It can be an advantage to get a not too expensive separate GPU. Also have a look at the PCIe slot layout, maybe this is also a good occasion to get a faster SSD (M.2, ..).
