I have a problem with the exe file after build.

Hi! I’m having a problem with the window of the exe file after building a sample I made on Unity. The normal size of the window is 800x600. When I resize the window, then I build & run it again, the size of the window doesn’t return back to it’s normal size. Please help me. I’ve been having this problem for a long time.

I would try deselecting re-sizable window in the build settings, then rebuild.
