DLL-FILE IS MISSING... Titanfall 2 won't launch due to some unforeseen issue

as of today for me, i have got the akin problem when attemting to run a game. 
after installing the game, every attempt to start it results in a launcher error: “Failed to load launcher DLL: \steam\steamapps\common\Titanfall2\bin\x64_retail\tier0.dll. The specified module could not be found.”
The game refuses to run at all. I have already tried multiple troubleshooting steps:

-- verifying the integrity of game files in Steam,
--completely reinstalling Titanfall 2,
--manually deleting the bin\x64_retail folder and re‑verifying files,
--reinstalling the EA App,
--checking antivirus exclusions, downloading,
--restarting the system, and running both Steam and the game as administrator.

Despite all these actions, the error persists and Titanfall 2 remains unplayable. I suspect the issue may be related to missing or corrupted system libraries, or a conflict between Steam and EA App, but I cannot resolve it on my own. I kindly request official guidance or a fix that will restore proper functionality.

help please
