The board is not lost!

Edit: With the UART bridge I can ampy put, but cannot otherwise. This suggests a power issue even though the capacitor from EN to GND is for that. I am still unable to flash firmware.

When I open Thonny, it says device busy. If I run esptool in terminal I get an invalid head of packet error. If I run esptool then immediately open Thonny, I get this:

Type "help()" for more information.

Other than this exact way, I cannot interact with the board. I also tried a UART bridge with same result.
