Game folder not Recognize

I was able to play the game yesterday (GMT + 8) and was able also to download the update earlier before the actual patch in the morning.
After restarting the pc due to other program’s requirement, Overwatch went to update mode again… but after updating it
All gone well as i play this morning
but right now
battle .net client wasn’t able to identify the Overwatch folder
Why is it like that? Did something happen that cause the game folder to be unable to be read like it was till this morning because of the patch?

That’s the error code being shown whenever i tried to locate the game again
