Error FR_NOT_READY with SDMMC on STEVAL-STWINKT1B board

Hi everyone,

I'm trying to manage the writing and reading of files on the SD card of the STEVAL-STWINKT1B board, but when I run an f_open it gives me FR_NOT_READY, I've tried with different SD cards but the result doesn't change, I ask if anyone has any suggestions on what it could be,

I'm working with stmcubeIDE v 1.16.1 and stmcubeMX v 6.12.1

the configuration on cubeMX is the following:

On stmcubeIDE in main project I only entered the function f_mount and f_open:

with the debugger I saw that f_open returns me FR_NOT_READY.
