Compile error 'Event' does not contain a defnition for 'current'

[jboss]

Hi,

I just changed my non-VR project into a VR project to be able to use it on my Vive. I did the following steps:

Enable Virtual Reality Supported in Player settng (am using Unity 2019.4.18f1)
Installed the packge OpenXR Desktop
Selected the OpenVr SDK in Player Settings
Imported SteamVR from the Asset Store
Imported Vive Input Utility from the Asset Store

And then I got 11 compile errors, all saying 'Event' does not contain a definition for 'current' in various files, such as 
Assets\HTC.UnityPlugin\ViveInputUtility\Scripts\ControllerTooltip\Editor\TooltipRenderDataAssetBaseEditor.cs(121,19)
Assets\HTC.UnityPlugin\Utility\Attribute\Editor\FlagsFromEnumAttributeDrawer.cs(128,35)

I figured I might need to restart Unity to reload dlls, but that did not help.

What is going wrong?

Thanks!

Sorry, nevermind. I had my own Event class which apparently caused the conflict.
