Just flash direct from esphome.

for that need a linux system, bcz windows ESPhome isn’t working threw an error.

Everyone needs a linux machine, full stop.

I am using WSL Ubuntu, Debian and Kali just for Esphome, but these boards are a few thousand miles away from my location and I have to remotely flash these without any linux machine there.

this was the solution.
connected directly to HA yellow via USB and flashed. according to ssieb there is a difference between “Direct USB flash vs. web serial”
