You may try to download and use the latest STM32CubeProgrammer v2.14.0 to see if the STM32H750B-DK is OK or not from hardware point of view.

[ZExpo.1]

Yes, I have tried that also, I re-installed everything from scratch now.

[jiangfan]

OK, be sure to enable the correct external loader: MT25TL01G_STM32H750B-DISCO for STM32CubeProgrammer to do the programming.

Going to observe here that if you run algorithms for other vendors devices against a Micron part that you can inadvertently lock blocks on the Micron device precluding write and erase, including mass erase, from working.

In these cases you need to remove the block protection level from the status register to recover the memory. 

[ZExpo.1]

Could You please specify how to remove block protection?

[jiangfan]

MT25TL01G datasheet will tell you.
