Qt not working on fresh windows install

[FleeXo]

Hey!
I worked with qt now for a while and hat to reinstall my Window.
Then I installe Vs19 and qt. But when I now wanna debug my application it isnt working. With mingW is isnt entering my main() and just showing up my debug console with <Press any key to return>. With the Vs Debugger im getting that CDB terminated.

I tried reinstall qt.
Tried also installing different Version (Im now at the newest, Qt 5.15 I guess?).
Repairing VS.

When Im trying to execute my app from the debug folder im getting qt.qpa.plugin: Could not find the Qt platform plugin "windows" in "". Here I also moved the qwindows.dll in the directory of the executable.

What am I lacking in my installation?
When someone need more information from me, just say it and I will post it :)

Hopefully someone can help me :)
Greetings Maxim.

@FleeXo What do you actually want to use: MinGW or VS19?

[FleeXo]

@jsulm I prefer to use the VS Debugger. I also just recognised that new projects are working just fine.
My project is also still working on my linux notebook.

@FleeXo Then did you install Qt for Microsoft compiler and did you install CDB (it is not part of Visual Studio)?

[FleeXo]

@jsulm CDB got installed for me with the Windows SDK. Well it gets auto completed atleast and also exists there. And I have installed QT for Microsoft Compiler :(

That are the logs when I try to debug.

I have the same issue. 2 PCS, use MSVC compiler, visual studio 2019. On one PC no problem, on the other one
Error: Change all symbol paths attempts to access '"C:\temp\symbolcache"' failed: 0x7b - The filename, directory name, or volume label syntax is incorrect.
I set the _NT_SYMBOL_PATH env variable to C:\temp\symbolcache but still no joy.
The application runs in release mode.

Thanks
