About Audient ASIO didn't work

My sound card is Audient id4 mk2.The driver softwear is already.
The Audient USB Audio ASIO Driver work in Bitwig, but not in syntheticV Basic.
Tell me why.My computer can use ASIO in SynthV weeks ago.But yesterday it didn’t work.I try to restart my computer but make no sence.

is it not able to be assigned? or you’re not getting any output? on the latter - sometimes the IO sample rate is different than the app sample rate. on the former, dunno, maybe there is a configuration on Synth V you need to clear and then reset.

The rate is same,maybe I should reset.

Although windows audio can work but I think ASIO maybe better. Lol
