Move Qt project from MacOS to Linux causes 255 error

I switched from MacOS Mojave to Arch Linux x86_64 today and I have installed ALL of the packages required for Qt and Qt Creator. When I create a new project and run it there is no issue. When I open my project that I created on MacOS there is NO error in any .cpp or .h file but whenever I try to build and run the project I get
exited with code 255in my application output. There are no issues nor warnings with my code. Why might my code not run properly?
Also I tried creating a new Qt desktop application and pasting code from the original project to my "new" project. I edited practically everything but the .pro file and I get 0 errors when I try to build but I still can't run the program without the
exited with code 255error.

Edit: I added
qDebug() << "here";at the top of my file but could not see it in application ouput or anywhere else. However when I enter the
build-myApp-debugfolder and run
./myAppI get the correct output from qDebug()! Anybody got any idea why the output in Qt Creator does not work?
Did you get any warning when compiling ?
Do you have gdb installed ?
