So I been playing Stellaris with DLC and mods and it has work fine up until last night. When I tried to launch the game from steam and click play from the Paradox launcher, it appeared with an error message. (Image provided below) I have tried validating the files and all is good. The strange thing however is that when I launch Stellaris.exe from the file explorer it works just fine. Even with the mods and DLC. When I disable the mods from the Paradox launcher and start Stellaris.exe from file explorer, the mods are also disabled as intended. I am not really an expert on computers and I am confused. Please help if possible.
