Exception while using Git Integration plugin on new version: 2017.2.3 : com/intellij/dvcs/DvcsUtil$Updater java.lang.NoClassDefFoundError: com/intellij/dvcs/DvcsUtil$Updater

I have updated IntelliJ today and now I am having trouble with git integration plugin. So far I see two problems :

1) The list of git-log changes is empty (even reloading doesn't help)

2) I cannot see small combobox with information about current branch. (Combo in right lower corner of IntelliJ, which contains also all different branches)

I saw in the intelliJ Log that there is an excetpion:
