JetRacer OLED Display doesn't work, Timeout Error, OS Error

I use Waveshare Jetracer-AI-Kit. I did hardware and software setup well so, when I first boot and run the examples it worked very well. However, suddenly, at some point, it doesn’t work.

There are two problems.
The first is that the OLED Display of the JetRacer Expansion Board is not displayed suddenly.
The second is that when the example (basic_motion.ipynb, …) runs, Timeout Error, OS Error happens.

This is the same issues with my problem.

It works well, but why it doesn’t work suddenly.
How can I fix this issue?
