Thanks for the report @gbrault! Would you be able to attach the Mu log to this GH Issue as well? It'll be really useful to us for debugging. File should be located in: %LOCALAPPDATA%\python\mu\Logs

Hello, Find attached all the logs I have from Mu. Best regards mu.log mu.log.2021-05-22.log

Thanks @gbrault!

This is the interesting part from the logs:

The device must have MicroPython flashed onto it before the file system will work.

Finally, press the device's reset button and wait a few seconds before trying again.

Looks like it first tried to open the ESP model files panel, it could not entre the raw-REPL mode and asked the user to unplug and replug the device. Then after doing that Mu crashes with the wrapped C/C++ object of type MicroPythonDeviceFileList has been deleted error.

The log was definitely very useful @gbrault! Hopefully we can replicate this problem following similar steps.

I believe this is the same issue from https://github.com/mu-editor/crash-reports/issues/185, so to try to keep things tidy I will merge this report there to track the progress in a single place: https://github.com/mu-editor/crash-reports/issues/185

We can continue the debugging over there, thanks again for taking the time to report this and provide the additional information @gbrault!
