I ask for help. Ghost task in the development board.

[red_Panda]

I used someone else's code (LED garland) and uploaded it to esp32, after that I uploaded my code. At the time of loading my code and when rebooting the board, I see how the previous code gives commands to the LED diodes. esptool.py --chip esp32 erase_flash brought no results. I feel like somehow there are two versions of different code on my board.
I am using esp32 devkit 1 and vscode + platform in arduino environment.
The strangest thing is that esptool.py --chip esp32 erase_flash completely erases my code and filesystem, but does not remove the "parasitic" code. those. after erasing, I still see how the LEDs work according to the previous program.

This question is no longer relevant. It turned out that the MCU STS15F101W was installed on the LED strip. This chip is the first, followed by the usual 2811, why the manufacturer did this to me is not clear, but apparently the sequence from the test firmware was written to this chip.
Now I don't know how to clear it.
Any ideas?
