STM32CubeProgrammer 2.16.0 fails to program STM32L433CC via USB

[Rob.Riggs]

Our customer attempted to update the firmware on their device which uses an STM32L433CC. Programming failed to erase and download the firmware on the device. STM32CubeProgrammer 1.4.0 succeeded in programming the device.

Customer is using a Windows 11 machine with STM32CubeProgrammer 2.16.0.

I have verified that the break occured somewhere between 2.14.0 and 2.16.0 as 2.13.0 works. I have also verified that the behavior is both OS-independent and GUI-independent as I experience the same failure on Linux with 2.16.0 STM32_Programmer_CLI.

This is clearly not a hardware issue, but something wrong with the DFU implementation in STM32CubeProgrammer 2.16.0.

A log file from the failure on Linux is attached.

This also affects STM32L4+ chips. STM32CubeProgrammer exhibits the same issue when programming the STM32L4Q5RE via USB DFU.
