1.8.1 Upgrade wont upload

I cant get any sketches to upload since updating to 1.81, even sample sketches wont up upload. Everything compiles just fine but I get"An error occurred while uploading the sketch" nothing else. I am connected to the board on USB-SERIAL CH340(COM3)
Have tried uno, mega and nano boards but nothing


Please do this:

  • File > Preferences > Show verbose output during: upload (check) > OK
  • Sketch > Upload
  • After the upload fails you will see a button on the right side of the orange bar “Copy error messages”. Click that button.
  • Paste the error messages in a reply here USING CODE TAGS (</> button on the toolbar).
