GUYS!!
I fixed this bug in my game, but I don’t know if this will work for others
When you open battle net you have to scan and repair in the settings options. You wait maybe 15 minutes or less.
**Then press search for updates and in the same settings options you can see a count like 52, 51, 50, etc. You have to wait 0 and start the game. **
I did this and I could play.
IM NOT SAYING THIS IS THE SOLUTION, IT IS SOMETHING THAT WORKED FOR ME
