Battery discharges while playing a game

So this never happened in the past, but today was the first time I noticed it. When playing The Finals, which this laptop runs fine (RTX 4050), the battery percentage starts to decrease, until eventually when it reaches around 21% the performance tanks and FPS drops to about 10 FPS (even on lowest settings).

I've played The Finals for a longer time on this laptop, and this has never happened before. I ran the HP support assistant battery checking tool, and it resulted in that the battery status was "normal". Could it be the charger? The first time it happened was today, and I was playing a game while simultaneously charging my phone (FP4, so supporting fast charging) via USB-C. That turned out to be a bad idea, honest mistake, it got very hot. But upon noticing I disconnected my phone and after charging back up to 30% the performance of The Finals became normal again, and the laptop didn't get hot anymore.

I made sure the Windows 11 GPU settings for The Finals are turned to RTX 4050 only, not automatic.

But now even though the getting hot doesn't happen anymore, the discharging and then performance dropping still does. I do notice that my charging block is still quite warm, I didn't feel how hot it got during the simultaneous phone charging and game playing. Could it be that I broke the charger by doing that? Or could the battery have gone bad due to the over-stressing and/or over-heating, but the program not being able to detect that?

I still have warranty left by the way.

After restarting, this notification just popped up. So my suspicion that the adapter has broken might be accurate? I could still try to see if letting it cool down completely (though it really isn't hot right now, just warm to the touch) and trying again tomorrow, it will work correctly again.
