Issue with RCC on flashing a blank project for STM32MP257F-DK

[MrVym]

Hello,
I have a stm32mp257f-dk and I would like to create an STM32Cube project for my board.
To be able to use the board, I have put in the eMMC the tsv file provided in the starter pack:
`en.FLASH-stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v24.12.05/stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v24.12.05/images/stm32mp2/flashlayout_st-image-weston/optee/FlashLayout_emmc_stm32mp257f-dk-optee.tsv`

My project aims to use the OpenAMP stack. I was able to flash the example which works very well but it does not have a .ioc file (which is necessary for my project).
So I used the STM32CubeMX Board Selector to generate an empty project.
First problem (screen 1), CubeMX tells me that DSIHOST, MDF1, and RCC are in conflict.
Since I don't need the Digital Filter and the screen, I disabled them.
I still have the RCC conflict. My code compiles but when flashing the project on the Cortex-M33, it crashes and here are the logs:

I checked the IAC exception 156 in the documentation and indeed it is related to RCC (screen 2). I see some logs inside the `/sys/kernel/debug/stm32_firewall/` directory.
I don’t really know what to do, I feel like I’m not heading in the right direction.
Would you have any idea knowing that I have not modified any code yet?
