Hi,

I used Sloeber IDE 4.4.3 and added a sketch with empty setup and loop funktion and get a file_opts error (No such file or directory) as well.
My device is ESP32 WROOM and I used ESP32 DEV Module as board in Sloeber IDE.
If I compile I get following error:

...

Build might be incomplete.

What I am missing please?
