I solve it by copying the folder of the 5.12.0\mingw73_32\plugins\platforms to the same folder that has the exe programe if there is a solution to solve it without this it will be better

qwindows.dll - for release mode, qwindowsd.dll - for debug mode.
Other plugins libraries may also be needed for you application. -

I compiled this version with OpenSSL 1.1.1a and put the necessary dll in the "_dll_for_app" directory (libcrypto-1_1.dll, libssl-1_1.dll). OpenSSL is used by Qt5Network for https connections.
MySql 5.6 - for MySQL Qt plugin
PosgreSQL 9.6.11 - for PostgreSQL Qt plugin -
I download it and add it to my QT 5.12 and it worked perfectly, really I appreciated that many thanks for you <3 and i hope they make a 32 bit release in the next versions if there is a way we can make a suggestion because most of us need our apps to be in 32 bit release, Thanks again @nayk

You should write a mail to the Interest mailing list or directly create a suggestion in Jira.
In either case, please provide a link here, so we can follow the discussion. Thanks!

the solution proposed by @nayk works very well, however this is a partial solution, because each time you want to update Qt, you need to build a new version of Qt for x32. I think there is a way to cross compile your application using mingw-64w, but i don't know how to do that. Maybe someone can instruct us how to do it!

@KATO2 Why do you want to cross compile? Just use MinGW32 to build Qt.
-
FYI: Qt 5.12.2 will ship with Mingw 32 packages included. UWP packages will be dropped.
-
@jsulm official QT 5.12.0 and QT 5.12.1 includes only MinGW 64, not MinGW 32 version was included.
@KATO2 Correct. Nevertheless, that's compiling Qt from source, not cross-compiling.
-
@KATO2 I'd say it may take four weeks until 5.12.2
So if you are in a hurry, you can still consider building Qt yourself.

@TonyK Honestly, I lost a bit track of the progress here.
But I doubt there will be a compiler change within the 5.12.x series - so it would be with 5.13 earliest. Anyway, this is the wrong place for wishes, the correct one is bugreports.qt.io
If you file a suggestion there, please provide a link here so we can comment and vote.
Thanks and regards
