Even if you create a default new project run, this problem still occur

Is there an error message when you start Blender from a terminal and run the game?

Do you have the canvas trait on an object other than the active camera? If yes, thats the problem and moving it to the active camera or changing the trait to a scene trait will solve the issue. Thanks for reporting this!

Nonetheless this should not happen. We should probably restrict Canvas traits to scenes to prevent this. Even if restricted to scenes and cameras this could cause problems when the active camera is changed.

Do you mean as shown in the picture? But it's still going to be black

Did you run a clean build? I can only reproduce this error when the canvas trait is on another object other than the active camera or a scene.

If a clean build doesn't help, can you send a test project (including the canvas file) please?

Thanks! This was due to an empty or nonexisting element name (so actually there were two different bugs, the one above with the trait applied to a wrong object and then this) and will be fixed in https://github.com/armory3d/armory/pull/1859.
