Since the recent update I have had issues with random spontaneous power cuts at full throttle limiting me to about 200kph and the rpm will limit me to 4th gear maybe 5th and the inability to deploy any battery in normal dry conditions with a full charge in both practice, qualyfying , race and time trial. It randomly fixes itself a little later in the lap but loses heaps of time and has no other fix. It can sometimes be accompanied by rapid opening and closing of straight mode however this issue was fixed by raising the throttle saturation. Before the update this was not an issue. It is mostly in my team but has been in time trial and both upgrading or changing engine in my team did not change it. The F2 mode seems to be fine but i have not tested it thoroughly. If it helps i have a logitech g29 wheel and pedal set on ps5.
Here is a video of one of the occurences of the power cut at full throttle with no warning and no deployment possible.
