interesting, didnt know this was a wider issue, mine started doing it within a month or two of getting it as part of the original batches but from the feedback at the time i just chalked it up to the finickiness with sd cards it was reported to have, wasnt until much later when the issue got far worse that i started suspecting i had a defect but i had too much going on at the time to do anything about it and mostly forgot about it. worth noting that the red channel on the display for mine isnt working right now, i may need to try reseating it again as i didnt realize the screen was also connected this way

found it… not sure who decided to put it together with pogo pins, but they have apparently been developing high resistance on the contact points over the years, cause i removed the screws, pried it apart far enough to see this design choice, then put it right back together suspecting it might have now fixed itself, which yes it did
