Timed out waiting for packet header.... Help needed ASAP Please- connetion error

Hi there!
Iam having an issue with my second ESP32 Board.
I get an error 'A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header'...
And have no clue what to do now to make it connect again.
It was working earlier today, i just noticed after i was reconnecting boards and this happened.
Please help i need to have it working ASAP and have no time to get a new board.

Best!

PS- all the tools and connection setting are the same and they were working few hours ago on the same board.
