Error: failed to erase memory

Good afternoon, I was trying to debug a program on my new stm32f103C8T6 chip using the st-link v2 programmer, but i always get the same error : Error: failed to erase memory

I have tried the procedure with multiple boards so i guess that the problem is software, here is the full console output :

I was having similar problems after I updated STM32CubeIDE from 1.9.0 to 1.10.1 but I had also seen it after I installed v1.9.0 too and forgot how I fixed it.

Basically, the IDE tries to run STLink at 24000 kHz which my target did not seem to like. I reduced it to 21000 kHz and things worked properly.

To set it, in the IDE with the project loaded, right click on the project name in the Project Explorer window. Properties->Run/Debug Settings. Select the project name and then 'Edit'. Under the 'Debugger' tab you can find the interface frequency.

My suspicion is that when I updated the IDE to 1.10.1 it reset the STLink frequency back to the default clock speed.
