PyPilot doesn't work after upgrade

[DjelaliTricks]

Dear all,

My pypilot don't work sine some day.

I made new install of Open Plotter and :

- IMU is found whith new OP install, but in pypilot control, is writen "None". I can see gains levels mooving
- when I make system update and Open plotter update, it loose every thing. Xhen launching pypilot_control from terminal it return "connect failed to localhost:21311".

When I connect the arduino to IDE arduino, nothing appears on the serial monitor.

I'm made differents test but don't remember every thing.

I'm also working on a batterie manager with INA219 and Nano Every, with USB connection, may it have damaged something ?

Is there easy way to test the Pypilot Arduino, like without IMU (connecting Vcc, GND, SDA SCL to the RPi) ?
Thank
