With the new patch, whenever I start a game (after everything is preloaded), I see a Generating Planets overlay in front of the system, and cannot choose a spawn. Once the time for the game to force spawns happens, I see my commander spawning, and can give orders, but the overlay still persists, like this: In addition to blocking my view, I can't give orders to spots beneath the overlay - it's very frustrating. Hope this gets fixed soon.
Although the picture is broken for me, this is usually caused by mods. Try running PA with the --nomods flag and see if the problem persists. (Or disable all mods in PAMM. The --nomods flag method is a sure-fire way though.)
If disabling mods doesn't do it, this one removes the overlay entirely. https://forums.uberent.com/threads/rel-decorative-panel-killer.66108/
Seems it was one of my mods. I disabled Enhanced System Preview, No Blackscreens, Show Secondary Colors, and Settings Manager and the problem went away.
no blackscreens is completely pointless by now for example. It's worth checking your mods once in a while
