Can you confirm what page size your kernel is configured to use? By running:

$ grep PAGE_SIZE .config

For Linux Kernel 6.9.3
root@mirela:/boot# grep PAGE_SIZE config-6.9.3 
CONFIG_MMU_GATHER_PAGE_SIZE=y
CONFIG_HAVE_PAGE_SIZE_64KB=y
CONFIG_PAGE_SIZE_64KB=y
CONFIG_PAGE_SIZE_LESS_THAN_256KB=y
CONFIG_HUGETLB_PAGE_SIZE_VARIABLE=y

I can upload config-6.9.3

Can you boot a working kernel and post the output of:

# ls -l /sys/class/block
