I have just recently run into this problem. I launch Stellaris and only a sliver loads. I have audio, but the load never happens. I was just playing the game yesterday perfectly fine. I saw other posts on these issues and have collected the logs and settings asked for previously. I am wondering if someone can help me out and fix this problem. I have already uninstalled and deleted all filed in document for paradox and stellaris in steam apps. I have also added stellaris.exe to the allowed apps in the ransomware.
