The program does not terminate

[krovit]

This runs and performs with no issues on my laptop.  Does changing the delays affect it at all?  Is there some race condition at work here, perhaps?

Thank you for the response.

The delays do not affect the execution or compilation of the code in any way. They can be removed, and it doesn't change anything.

I tested the code on three PCs with Windows 10 in the versions I mentioned, and the last one that works is 3.12.0.

In the subsequent versions, the execution gets stuck, and as I wrote, strangely, the execution continues, but the output on the screen is not coherent. I have to forcefully terminate the execution.

I would like to add that the compilation with version 3.12 is very fast (the first time. With all versions, it is always slow - I don't know why), while with the later versions, it is very, very slow.

For now, I will stick with version 3.12, but I am sorry to miss out on the updates.
