Dash music tune at startup & check hybrid system

Hi Everyone. Got a 2010 prius IV at 178K miles here, had it since day one and never had any issues in the past, literally zero.
Yesterday was taking off at the traffic light on a highway, at some point for a split second i felt unusual loss of power and then there was very loud clunk from under the car, like something snapped. 4 dash indicators lit up - brake system warning (encircled exclamation mark), check engine light, ABS light and VSC light as well as check hybrid system warning. Car did not shut off, i could not stop the engine at that very moment where i was so i proceeded about a mile to a safe place and then turned it off for inspection. Did not see anything abnormal under the car or under hood, so i started it again, 4 lights came back on, luckily car was still operable, however, more like a regular gasoline car. I drove 3 miles to home, felt that electric engine does not take part at all, all power comes only from a combustion engine, car could move only on a light gas pedal. If i pushed it somewhere more than 20%, there was high rev noise but no gain in speed. When braking, there was no regen, just disk brakes.
This morning i wanted to start it to go drop it off at toyota, but car didn't want to start, i turned it off and on 3 times, on the 3rd attempt there was a music, some kind of simple tunes played from the dash and the car started so i slowly proceeded to toyota (about a mile). Still no news from them. Anyone has an idea what this dash music tune means and what could've snapped so loudly? Thanks in advance!
