I know this seems a glib and unthought out response, but your issue could be due to RFI. The mechanism is that a USB audio connection may get interrupted by RFI and when that happens the operating system responds by "un-plugging" the device and dropping the device driver connections. When that happens it is possible for audio streams to be re-routed to other devices (I would guess the default device), WSJT-X would be unaware of this and will continue in ignorance.
The ultimate test is to try and reproduce the issue with minimum power, preferably into a dummy load or a different aerial with a good match. Other indications are that the problem does not happen on all bands.
The convenience of USB connections that automatically hook up drivers (a.k.a. hot-plugging) is not a "Free lunch" and there are some down sides.
