TX0 RX0 Data is corrupted, I am not able to flash ESP32-WROOM-32

Hi!
SOLUTION: I have found it has to be the computer, moving to another one solved the problem, so the design was good.
Attached is an image of the SCH of my ESP32 device with all the pinouts.

I am trying to program the module, but it is not working, nor is it being detected by IDF.
Checks I have done:
- 3.3V is stable and works well. LDO is working and able to give at least 500mA to the module.
- BOOT, EN in low when I power the module ON and then disconnect the cable to EN and let it in normal state.
- TDI short-circuited to GND when powering the module.
- Using two different UART-USB modules and different USB ports.
This is what I can see in the terminal program:

Any ideas? Best,
Rob.

Don't have both a terminal as well as the flasher active at the same time.

Thanks for your response; I opened both to make the screenshot, so there is no different behavior having the flash tool opened without a terminal.
