The program has unexpectedly finished (Windows)
-
Hi, this is my first time Qt developing. I already installed all environment, but have a big trouble at start.
Immediately after installation I ran first example “Address book example” and it worked. I didn’t even change any default properties. But another day after reboot (I don’t remember changing anything in system settings) everything went bad.
If I create “Hello World” console application, it successfully builds and runs:
- built with MSVC console window opens with no output “Hello world” (only “Press <RETURN> to close this window...”)
- built with MinGW console window opens with proper text
If I create blank widgets project or open any embedded QT Creator example, it successfully builds, no any errors, but after run it instainly falls with the following messages:
The program has unexpectedly finished. The process was ended forcefully.No difference between MSVC and MinGW.
My environment:
- Windows Server 2019 1809
- chocolatey package microsoft-visual-cpp-build-tools (python extensions builds successfully)
- MinGW 7.3.0 (installed with Qt Creator installer)
- Qt 5.12.5 MSVC 2015 64-bit
- Qt 5.12.5 MinGW 7.3.0 64-bit

Hi and welcome to devnet,
Did you get any system update before rebooting ?
Do you have that crash in both release and debug mode ? -
No, I did not get the updates. Yes, it happened in both release and debug. In addition my python 3.7 package PyQt5 was broken too. I tried several hacks to solve this problem, but nothing avail.
Then I was radical and removed all development tools (python, qt, mingw, visual studio, etc), cleaned all settings files and install all from scratch. It works great as if nothing had happened.

Nothing like a hard reset...
Anyway, glad you are back on track. Happy coding !
