Ninja: error: FindFirstFileExA

Hello,

I have been successfully developing on a custom nrf5340 board using nrf connect SDK 2.3.0 and VS code for a while now. Suddenly I am seeing a new ninja error FindFirstFileExA when attempting to do a iterative build or flash. However I am able to successfully run a pristine build which does generate the appropriate zephyr/samples/hello_world/build/zephyr/include/generated directory, but cannot flash or rebuild after running pristine. Logs below of successful pristine build then failed rebuild.
