libEGL Error

When I ran the go2_train.py in the rsl_rl folder, I came across the following error message.

I tried to reinstall libnvidia-egl-wayland1 but it didn't work. And I thought the error might relate to my CUDA version or my memory limits. When I tried to install another CUDA, it conflicted with the existing one built by pytorch.
But when I run fly.py with CPU, the error messgae also occured.

I have solved the problem by installing 12.6 version CUDA with .deb format file then reboot.
