Release mode app not launching. Visual Studio version 17.5.1

@Lighting123
Please elaborate by providing details as what does Sometimes it doesn't show any window and sometimes it does show a window. mean. Does it render text or not ? Does it show any elements on screen ?
What device does this behavior occur on ?
Can you provide a minimal code sample that replicates the behavior ?
Also, if you build via terminal / command line instead of IDE, do you get same behavior or not ?

Sometimes it doesn't show any window and sometimes it does show a window.

Also, did you mean a possible silent crash? Anything logged at the Windows Event Viewer?

Well sometimes it launches as a process in task manager but doesn't display any window while other times it does display a window and building it with command line it also does the same behavior.

Are you trying release mode on windows desktop platform, like flutter run --release -d windows or flutter build windows ?
The .exe generated you are trying to launch but it is not launching properly ?
Can you provide your pubspec.yaml and also check at your end if any of the plugins might be conflicting ?
