After updates, the executable file format used with the game's core files is updated, causing antivirus applications to perform what we call a false-positive action.
A false-positive occurs when certain files or file extensions are incorrectly confirmed or shown as positive by protection programs during data evaluation or scan results, even though they are not actually present.
For such situations, our team contacts all antivirus companies that cause problems after each maintenance update, including Windows. However, because this process is slow, we may encounter errors for a while.
It's normal bug of the game sometimes theu fix it sometimes it will retirn after few patch, to fix this problem for the main time, disabled your anti virus, and reinstall the game.
