What does "Attempted to write to a non-existent pipe" mean when running an application on windows from php?

Question

PHP

Greetings!
When trying, execute the following php script:

$cmd = 'd:\test.bat';
pclose(popen("start /B \"\" ". $cmd, "r"));

in test.bat:

@echo off
echo Test

CLI hangs with messages:

Попытка записи в несуществующий канал.
Попытка записи в несуществующий канал.
Попытка записи в несуществующий канал.
Попытка записи в несуществующий канал.

due to launch with the /B key, Ctrl+C does not work. Only "Ctrl+Break, Enter" helps, while the following gets into the console:

...
Попытка записи в несуществующий канал.
^C
"♥" не является внутренней или внешней
командой, исполняемой программой или пакетным файлом.

Of course, I'm very glad that Windows shows me love and sends hearts ... but I can not figure out what the problem is ..
Previously, everything worked fine. I can assume that everything will work on a "clean" Windows. Presumably, the problems started after updating the video card drivers with its native NVIDIA Geforce Experience utility, which at least lost the PATH environment variable, deleting everything and writing down only its path there. I restored it, focusing on the laptop, but mb that was not all ..
If anyone came across, please tell me what the problem is, where to dig.

Good time!
I have a similar situation with Laravel commands, in particular php artisan backup-commands:database
Have you figured out what that would mean?
