This was a case with the 1.30.0 player update. 1.30.0 added in GPU accelerated UI rendering. It didn’t just work like it was supposed to. 
I rolled 1.30.0 back some hours ago. You can uninstall 1.30.0 and reinstall 1.29.1 downloaded from our website. I’m in the process of creating a 1.30.1 which works around the issue through auto update.
Let’s consolidate over in App starting up to blank or solid black screen?
