Some info I neglected to share is that the first song still plays all the way to the end, but the visualization is frozen and the interface becomes unresponsive with a Windows busy icon appearing if I try to click on anything.
I got the freeze to happen again, but the display managed to resize to my TV completely and work fine for 5-8 seconds before occurring. I killed the MC process and started it up again and it seems fine now. I think it only happens the first time I open MC after a (re)boot. I got the log file (attached), but I'm not sure how useful it is because the timestamp for when the log starts is with the new fine session and not the frozen one. If it is in there somewhere, I didn't do anything between the crash, killing the process, opening and generating the zip file.
