Horizon View Client does not work after upgrading to Chrome OS 45

Is there a known problem with Chrome OS version 45?

My Horizon View client was working without issues, but after upgrading to Chrome OS 45, the Horizon View app starts with a blank screen that shows just the Horizon View logo in the middle. Nothing happens. I cannot connect to a server or start a VM, it is also not possible to do any configuration. I restarted my Chromebook, de-installed and re-installed the Horizon View client. Nothing helps...

I am working on a Chromebook Pixel 2015. Chrome OS is:

Version 45.0.2454.86 (64-bit)

Platform7262.52.0 (Official Build) stable-channel samus
