Thank you for the report!
Is it this board; https://randomnerdtutorials.com/esp32-cam-video-streaming-face-recognition-arduino-ide/ ?
Which Thonny version are you using? The latest in 4.1.1.
You could try different submit_mode

the esp32-cam ai thinker board. thonny version 4.1.1. I tried to do what you wrote to me, but it didn't help. on the website https://bipes.net.br/ide / everything works fine
the esp32-cam ai thinker board
This needs a separate programmer "shield", right? Are you using the one with CH340 chip (https://makeradvisor.com/tools/esp32-cam-mb-usb-programmer/) ?

I've got the same problem. I'm using the module in the link you just sent. My error is a little bit longer, here the photo.
I don't think the problem is in the firmware anymore cause I just updated it to 1.20 ("esp32-20230426-v1.20.0.bin") using the configuration of the interpreter. My thonny version is the same 4.1.1 I haven't written any code on the board yet, I opened Thonny and this message has been there since then, either I stop and restart or I do anything.
I think was able to reproduce this problem with another board using the same serial adapter.
I noticed difference in how Pyserial (the library Thonny uses for talking with the device) manages to start a working connection compared to command line tool tio
. With minimal experiment Pyserial produced a "stuck" connection (no output) the first time after the device was plugged in. After I made a connection with DTR/RTS=False, the device rebooted and this time the connection was working. I could use this approach as a work-around in Thonny.
Unfortunately I did not learn what tio
does differently so that it doesn't require this reboot to work properly. I did manage to get the device or USB connection into a state where even tio
could not read anything from the device. Can't explain.
I made these experiments a few weeks ago, so I'm not sure whether it was in Linux or macOS. I believe it was Linux (Ubuntu 23.04).
For Thonny 5.0 I plan to reveal DTR / RTS options in MicroPython configuration page (#2764). Until then you could try whether putting dtr = False
and rts = False
directly into ESP32 block of the configuration file helps. See https://github.com/thonny/thonny/wiki/MicroPython#advanced-configuration for instructions.

Thank you for your response, I tried it, something new has been displayed but i got the same error, here's the screen.
EDIT!! after pushing the reset button the board connected without error, thanks!
I'm getting the same error, is the configuration change similar to the following? it still fails to connect after I changed config like follows, and the configuration is automatically reset by the software
[ESP32]
port = /dev/cu.usbmodem544C0050241
interrupt_on_connect = True
sync_time = False
local_rtc = True
restart_interpreter_before_run = True
dtr = False
rts = False
Thonny verion is 4.1.3 board is esp32-c3

I just pressed the reset button and everything started fine, I haven't changed anything in the configuration file
The serial connection to a MicroPython device is sometimes full of wonders for me as well :) You could play with different dtr
and rts
values to find out which is best for your platform and MicroPython device.
Downgrading Thonny's version and getting the latest beta hardware Fireware is fine with me.
