Knomi v2 Can't flash through VS code

[borysne]

I'm trying to flash Knomi v2 but unfortunately nothing works! The firmware is built in VS code using the platformIO , but when I flash the screen is always black, I tried different firmware, all the firmware that is built through PIO does not work! I tried to flash the firmware built by PIO via USB, and flash_tool did not work! To restore Knomi after firmware failures, I use Flash_tool and flash the Bin file from the official website! I've already tried everything and can't figure out where my mistake is??? please help I recorded a video, maybe you’ll see something that I didn’t notice! https://youtu.be/3zP8yZpm3ds
