As confirmed by an STMicroelectronics employee in this thread some STM32H750 chips have been shipped with fused off HASH and CRYP units resulting in 100% failure rate to write to any of their control and status registers. The date codes listed in README.md for STM32H750 boards fall in the range of potentially defective chips.
Do your boards as offered on AliExpress ship chips containing usable HASH and CRYP units?
