Black screen after unlocking with fingers

[Charcoal]

After the latest beta release, the fingerprint scanner is much faster, but now I have this issue where I place finger on screen and it "unlocks" to an all black screen and never goes to my icons. I can see the status bar and I can do the back gestures from the sides of the screen but it does nothing. I have to use power button, shut off the screen and use finger again. Most of the time it goes to my icons, some times it goes to the black screen again and I have to do this process again to get to icons. See below.

Photo attached of the issue.

The next update should fix this.

I have the same issue. Also had a weird issue where the dock icons disappeared at one point.

Same, but Beta 5 on the way. Has it as a fix in it's Changelog.

I still have this problem.  Some screenshots come out black and others don't.  Very annoying
