Flash write failures, after having flash waits wrong for a while

I switched the sysclock to 72 MHz without setting flash wait states to 2.

After figuring that out I corrected my code but the MCU now gets many flash download errors. The failed bits are all still 1's.

Can the chip actually be broken?

My code works on another development board (same model), which however doesn't have all the prototyping stuff I have soldered to the first one. The added prototyping circuitry isn't the problem, it worked fine before I bumped up the clock.
