After running simpletext.py script my other devices connected to I2C are invisible

After running simpletext.py when I use “i2cdetect -y 1” displayed information is slowing dramatically also connected devices are not visible anymore. The only fix that I found Is to restart the raspberry Pi.

I trying to enable the second i2c. But the situation is the same.
I think it must be because of the clock but can’t find the reason.

I thinking about buying another module: Overview | Adafruit RGB Matrix + Real Time Clock HAT for Raspberry Pi | Adafruit Learning System but I’m not sure it will help me.

Specs:
Raspberry Pi 3 Model B Plus Rev 1.3
Leds module : Adafruit Medium 16x32 RGB LED Producent code: 420

You can see the connection in that pictures:

I trying to do anything but can’t understand and find a solution for that. If anyone can help me with that or give any hints about what should I do I will be very grateful.

Bump, But can I bump my post?

not the answer you’re looking for, but this library changes a fair amount of things to make sure it gets all the IO and CPU it needs (as real time as possible), and in parallel 3 mode, uses every single I/O pin available.
it’s just not been well tested to work with others subsystems, and if you need them at the same time, you’re a bit on your own unfortunately.
