Save it and run it again, i will not run

I’m studying a navigator
And it was definitely done before the fuse ended.
and I certainly saved it.
But it doesn’t work when you load the project back into the fuse.
No errors, no problems are indicated.
The only white screen you see when you first run the fuse.
What am I supposed to do?
I don’t know, please help me.
I’m window10 user.


Hi Bella, could you please share your code and show us what’s in the log tab that is next to the problems tab.
