Switch between ArduinoCloud and local IDE

Official Hardware UNO Family UNO R4 WiFi

I after playing with the cloud, I wanted to try local development, so I pushed local code that simply output log on serial (Serial.println). I tried to get back on ArduinoCloud, but my UNO R4 no longer connect to the cloud. I tried various things: restart the provisioning step, connect on the could from sample sketch, thus installing new libraries ...

How to restore the connection to ArduinoCloud ?

I fear that all these libraries get installed on the board and take space. Is there a way to see/free memory content on my board ?

There are samples to display Heap on AVR boards like AVRHeap. Other boards most likely have similar.
A rough way to check library overhead is to create an empty sketch for the board you want, look at the compile stats, then add the library and look again. Subtract the numbers to determine fixed overhead. In use, a library could use even more.

I got it ! I just needed to reboot my computer. I probably had something opened in the background using the board which prevented me from completing the association.
