Freeze screen and problem with gpio

[aquapark]

Raspbery pi 4
Rasbian legacy lite
Trigger video with gpio
Pins 26, 20, 16 shorten to the ground on rpi.
Default video and three more.
I have followed step by step with your read me instruction.

First of all thank you for your great work with this script because is very helpful. When I start test I have some problems with following things:

1. When the default video starts everything is OK and the buttons on gpio work perfectly but when I Don't do anything and default video is playing on loop is doing great but when I want push any of three buttons I must push any of button twice because when I hit it once nothing happens. It looks like this script sleep and push button for the first time switch off this sleep.
2. When your program run 24h/day when the default video looping I must switch off raspberry power and then power on because the screen is freeze or I must push any pins button to switch of some kind of sleep.

I will be very grateful for your answer and help.

Config and support programs/libraries:
Disable console "screensaver" so that it never goes blank by adding to the end of "/boot/cmdline.txt":
consoleblank=0

The author mentioned a way to close screensaver in the readme, I hope it will be useful to you.
