Cant launch the game from steam since yesterday

Hi, i cant launch the game from steam since yesterday night.

First it crashed, than it tryed an update but before the update finishes i get an error saying "Inhaltsdatei gesperrt" in german. Something like "Contentfile blocked" i guess?

Did someone else got this message? I dont know what happened or whats this about.

I tryed deleting the poe2 Folder in Documents and deleting the steam cache but that didnt worked either.


Please help
