G14 (2022) abruptly shutting down when playing relatively light games

I have a G14 (2022) with an AMD Ryzen 9 6900HS, 24 GB of RAM, and an AMD Radeon RX 6700s. The GPU's driver version is 31.0.24033.1003.

Over the past several weeks (and only occasionally before then), I have been experiencing random shutdowns while playing the only two video games I play these days: Genshin Impact and Honkai: Star Rail. (This is similar to someone else's problem, here.) This has been becoming more and more frequent, happening practically once a day, now.

I use GHelper. I was keeping an eye on GHelper. The last time the laptop randomly shut down was when I was playing Honkai: Star Rail, reaching a CPU temperature of 70° and a GPU temperature of 73°, which does not seem particularly unusual. I also have an external cooling pad for the laptop.

Turbo boost is disabled.

What could the issue possibly be?

It happened again, the second time today. This was with Genshin Impact. CPU and GPU temperatures were both around ~71°.

I have reinstalled the GPU drivers. They are now 32.0.13031.3015.
