I'm having this issue, too. :( Brand new save as well
This actually happens if you played before the update but started a new game after updating.
You can try to load an old save once (this will "reset" the game) and then continue playing your new save, or delete everything from this folder
C:\Users\*username*\AppData\LocalLow\Glitch Pitch\Idol Manager\data\cache\portraits
Another option is to open your new save file with a text editor and replace "version":"Beta #11" with "version":"Beta #10"
Unfortunately, none of these things worked :(
Something I noticed was that although only the blurry screen came up, I could still hover my mouse over where the portraits would be and click there - but doing so would crash the game immediately.
After I changed Beta #11 to Beta #10, it no longer crashed when I clicked the ghost portraits, but I couldn't get out of the screen either
Okay, that's weird. Are you playing on a laptop?
Please upload Player.log and Player-prev.log to https://file.coffee/ after it happens again
