error code - 0-0X00000209

The issue occurs only when I press Escape on my keyboard, this happens when im in uplay launcher or in Rainbow Six Siege itself,
Afterwards I get error box with a uPlay crash, then game tries to reconnect for good.

For now I restarted my PC and Router many times, still nothing, also I checked and unchecked Cloud Saving in settings but still nothing,

This error happened to me on July 13, before everything was great and didn't get any errors.
