Upgrade your Kotlin plugin.

The simple way (Recommended).

Double shift -> Plugins -> Updates -> search Kotlin -> Update! -> Restart AS

Manually way (If you need).

1) Download Kotlin Plugin manually from this link.

2) Double shift -> Plugins -> (Settings) Icon -> Install from disk -> Choose that plugin.

3) Restart.

If you can't update it, you can just disable it like this: Double shift -> Plugins -> installed -> search Kotlin -> right click -> Disable -> OK reopen this dialog again: Double shift -> Plugins -> installed -> search Kotlin -> right click -> Enable -> OK -> Restart IDE And it'd done.
