System.IO.DirectoryNotFoundException

Hi Marc thanks for the 3.5 update to the Uduino

After importing Uduino to Unity (2020 23f1) I bring in the Uduino prefab to the scene, and in inspector can 'add directory' and then 'fix the 2.0 to 4 .net version'. Both get a green step done. Then I click, I'm ready. I chose Arduino Leonardo this time, but it happened with the Mega first as well as uno.

In the next part I get Step Done at the top, and a notice about Arduino Mega (whether I am using Arduino mega or not, which I wasn't so I chose the I m not using...)

Then finally it says, Uduino has been updated, so I go on to click 'update uduinos arduino library' ( and I haven't changed the path from previous step).. and that throws the errors attached. I can't seem to click discover ports without that step.

On going to the Documents/Arduino/Libraries folder the uduino folder seems to be there, but weirdly the Arduino folder inside the actual Unity project goes empty !!! Weirdly there is also a .meta file created for everything inside the main folder.

Only silver lining, when I click discover ports, I can see the /rx port blink on the board. Help appreciated. Thanks again.
