Thank you.
Reinstalling the driver with a lower version as answered, solved the problem for both RTX3070 LAPTOP / RTX2060 SUPER. It seems that the previous floating-side problem has also been resolved. (Intel driver reinstallation without turning off)

However, a warning message like the image below appears.

And may I know when this problem will be resolved??
I wonder when the latest version of the graphics driver will be available.
