I keep getting a File I/O error

I keep getting an error when i press play. it first shows me easy anticheat loading and then i get a file I/O error. i cannot even play the game. it says “press repair” but all that does is make the launcher load for a while and then it does nothing at all. does anyone know a fix for this issue?

Try the basic restart of the computer first. Sometimes it just goes away by itself.

I try these normally if it does fix itself:

Then restart again.

The launcher repair I normally try last.

if you play through steam try to repair game files through it
