Can t upload project

Hello, I have Arduino Leonardo and Widows 10 and if i want to upload any sketch it is sth like that:

avrdude: ser_open(): can't set com-state for "\.\COM5"

I ve checked all my ports, i downloaded latest ver of arduino and still doesn t work. Any suggestions ?

41,000,000 results on Google (can't set com-state for Leonardo), ranging from using a different cable to manually removing the drivers and reinstalling.

Please list what you have already tried so we don't waste time making redundant suggestions.
