Apparently, the rear wheels were lifted off the ground due to the colliders under the floor touching the ground (this was also confirmed by the fact that the front wheels still had grip).However, simply moving it up would result in a significant drop in downforce, so I offer the following suggestion.

Since the rear tires are buried, we recommend changing the following values:
-tyres.ini-
[REAR]
NAME=Slick Soft
SHORT_NAME=S
WIDTH=0.310
RADIUS=0.355 ←
This should minimize the loss of downforce. If the AI is not behaving well, try the following.
