i used 52833 prgramming the sample in VS code(DF coneectionless RX) , it was ok few days ago.
but now, it has fatal error when it builds or flash in board.
i didnot change much content. i tried fixed it , I have confirmed some files exists in the path.
i want to know what happened and how to fix.
IDE version:
WIN10
nRF Connect for Desktop v4.0.1
toolchain manager v1.2.0
nrf connect SDK v2.0.0
zephyr sample direction finding connectionless rx
zephyr sdk 3.0.99
some happen
or
I have completely deleted the build folder before rebuilding ,but it still has fatal error 
i remember that i don't change the configure.
prj.conf

dfegpio1-gpios = <&gpio0 4 0>;
dfegpio2-gpios = <&gpio0 28 0>;
dfegpio3-gpios = <&gpio0 29 0>;
};
i could use it few days before, but idon't know why it has some problem.
thanks for your help
