PPK2 is stuck in bootloader after trying to flash the latest firmware on Power Profiler 4.2.1 (Windows 10).
The error is "serialport could not be opened ". The same issue is reported in Programmer.
The prompt comes up to flash the firmware but hangs when clicking Program.
On Linux there is no error until hitting program but then it reports the errors at the bottom
