Everytime I try to open to the game I get a fatal Error:
[File:C:\UE4\CSAND\Engine\Source\Runtime\PakFile\lPlataformFilePak.cpp] [Line: 3791]
Trailing magic number (0d) in
‘…/…/…/ConanSandbox/Content/Paks/Maps.pak’ is different than the expected one. Verify your installation.
This is happening after the last patch of April 28.
What can I do to solve it?
I am by no means an expert and only guessing, but from what I see there, it appears as though “verifying the integrity of game files” in Steam may be a possible solution to your issue.
You can do this by right-clicking “Conan Exiles” in your library, selecting “Properties” then “Local Files” and finally the actual “Verify Integrity Of Game Files” button.
Do what DeadSpine said, should solve that one.
