Same on the Tonport UX2 on Win11 when changing ASIO from 16bit to 24bit. It never saves this setting even though the PC Sound Settings show "48Hz 24bit Studio" yet it records into Cubsae13 as 24bit 44.1Hz
Not sure I need be bothered by this but am looking into listening from PC Stereo Output by using one of the solutions from vb-audio.com/Voicemeeter/index.htm to mix ASIO to avoid needing to change ASIO4ALL lots just to record takes using ToneportASIO. It will crash by doing this too to lose Sound otherwise.
Here is same issue... perhaps changing to 24bit makes no difference then when the DAW records at 24bit...
