It works when USB-CDC is disabled and it works if USB-CDC is enabled and serial monitor is open, but it does not word if enabled and no serial monitor is open. So i use the serial monitor to debug and all is OK but then the same device doesent work if not connected to the PC?
Is there a work-araound?

Can't give you a workaround for code you haven't included.
Search on https://github.com/espressif/arduino-es ... Aissue+cdc for known issues
