STOP, TRAVELER!
Stop, traveler! This soil you walk upon unknowingly
Is where an era came to an end.
Bend down and listen, this quiet mound
Is where the heart of a nation beats.
This lonely, silent, forsaken hill
Is where all thoughts of heroes turned to blood.
Drop by, press your ear to this silent mound,
Because this flood is where a nation's freedom was won.
Greetings from Türkiye
All of this belongs to Gemini.

Based on this topic, I will show you how to fix the two bugs that cause 99% CPU freezing.
CWebBrowser
Regarding the other CPU locking issue:const auto app = new CPythonApplication;
When I changed this to:CoInitializeEx(nullptr, COINIT_MULTITHREADED);
it got fixed."
Example of a CPU locking fix.
