Battery icon shows question mark when unfolded and charging

Recently i've been having this weird issue where my Google Pixel 9 Pro Fold will display a question mark over my battery icon, and the settings app will tell me that there was a "Problem reading the battery meter." This seems to happen sometimes when the device is simply unfolded, and especially when i plug it in, and then unfold it, and the issue doesnt seem to go away until i unplug the device and fold it back up, or at least until i fold the device again. From a quick search online it seems this might be a hardware issue, has anyone else had this issue and maybe know a fix for it? For added context, i am currently running GrapheneOS, but the behavior im seeing doesn't really indicate a software bug, especially since i updated the OS lately
