War thunder Steam file failed to validate and will be reaquired HELP

after a few games of playing War Thunder, i will notice that my game becomes extremely stuttery and the frames will drop durring a game. i go to validate the files and Steam says that 1 file has failed to validate and will be reaquired
this is a recurring issue and uninstalling and reinstalling the game does nothing to fix the issue nor does doing the same to the steam app.

can anyone point me in the right direction to resolve this thanks
