About the projects

I Have to stop the couses now, Tried A few times and Getting stuck allmost Every step.
Screens dont match and getting weird errors in C++. Even changed the bug issue.
Started project Bull Cows and got stuck At item 45.
so tried to start Building Escape (started it like 15 times now, delete and start over)

Is it due to Engine 4.25 ?

There’s not that much different from 4.22 and 4.25. Could you give examples?
