Why don't touchpad clicks work at the same time as pressing letters?

Question

Keyboard

Why don't touchpad clicks work at the same time as pressing letters?
I find that in shooting games the left click of the touchpad is not pressed while running (w).
I check and it turns out that when you press any letter (key) of the keyboard, the touchpad click is not pressed at the same time.
When I'm standing, the touchpad firing is normal, but after each press of a letter (running, etc.), pressing the touchpad does not work for a couple of seconds. There is some delay after the keys.
Previously, on older versions of windows 10, it definitely worked.
Is the problem in some keyboard shortcut settings or touchpad driver? (There is no new touchpad driver and will not be - mine is outdated.) The native asus synaptic 32 bit driver is not installed. Some standard Windows is installed, There is no touchpad in the task manager, but it works except for simultaneously pressing letters with the keys.
You have to use ctrl instead of left click at the same time as w

The touchpad driver has a function to suppress accidental clicks. Ignores button presses for some time after using the keyboard. Usually disabled in the device settings or by witchcraft with the registry
