Lost ability to input text in Qt Creator when large amount of compiling errors appears in the console

NOTE: The steps to reproduce are quite specific, but I hope they will help to find the root cause. 

Linux Ubuntu 22.04

Qt Creator 12.0.2

Steps to reproduce:

1. Open example - https://doc.qt.io/qt-6/qtwebengine-webenginequick-quicknanobrowser-example.html
2. Open main.cpp file in the editor and add 'qt' word at the beginning of the file.
3. Open tab 'Compile Output''
4. Click "Run"
5. When the run is completed, click in the editor and try to write anything.
6. Repeat step 4 and 5 if the issue does not occure after first time.

Expected: I should still be able to input text in the editor despite the number of errors.

Actual: I'm not able to enter any text. It's not just the editor, but also other input fields are affected. The app receives the signals from the keyboard because when I hold CTRL button I see functions highlighted. Attaching video for more details.

Reproducibility:  100%
