On windows you can use STMCubeProgrammer CLI too for DFU.

Simply check flash content with stlink or ?

I am trying to upgrade the uC via software so i guess the only option for me is using the DFU, however when i call

system("sudo dfu-util -a 0 -i 0 -s 0x08000000:leave -D "path to file");

i get the error from above

When i am doing it from the STMCubeProgrammer interface all works well (even though i had to downgrade STMCubeProgrammer version, the latest one was crashing)
