Laptop issue with video

I have to unfortunately be this vague because I have no clue what the problem is. My Lenovo ideapad Gaming 3 is working fine otherwise, but every now and then, with no regularity, watching a video via Media Player Classic it will just freeze and that seems to seize up the player completely. Trying to click or close just locks it. The rest of the computer seems to be fine at this point, the fan doesn't speed up, nothing that would suggest an issue. But if you try to reboot via Task Manager the reboot time can be forever. The only thing I've found that works to get the computer back is to hard reset. These videos are on a Samsung m2 in an external Sabrent enclosure connected via USB-C. Any ideas? Is this just MPC?
