There seem to be two different problems.
1) The magenta screen. When this happens, trying to fast forward or rewind does not display the overlay, and it's basically frozen until I hit the back button and wait a few seconds. The files with the frozen magenta screen indeed have both Dolby Vision and HDR10+. This seems to be the same issue as the known bug linked in comment #4. I started playing about 10 different 4K videos, and only two had this problem
2) The black screen: stuck in pause mode. This affects all but one of the 4K videos I tried. Unlike with the magenta screen, when I use the left/right arrows, the overlay displays, and it fast forwards and rewinds. However, it is stuck forever on the frame without playing. So basically, the reason that it initially shows a black screen is that it's stuck on the first frame. When I fast forward, it shows the frame I fast forwarded to, but it doesn't actually play. In other words, it's basically paused, and trying to pause/unpause toggles the play/pause icon, but it never starts playing.
This second problem is happening for all but 1 of the 4K videos I tried to play. None of these files had both Dolby Vision and HDR10+, and the player behavior is different, so it definitely seems to be a different issue than the first one.
All but one of the 1080p videos I tried to play worked fine. The one problematic 1080p video had the black screen (stuck in pause mode) behavior in the player.
I'll share a few instances of mediainfo here.
This is the 1080p video that has the black screen issue:
