My Pixel 7 just updated to build UQ1A.240105.004.2024010400 (Stable release channel) and when it finished applying updates, I got a system notification: "File System Error was Detected." Tapping it displayed a bug report, copied below. (additionally, one weird thing that could be related is that my phone rebooted by itself to apply the update, even though I have Settings > System Update > Automatic Reboot turned off.)

Anyone know what the heck is going on here? I have no idea how bad of an issue this is. The phone still works fine, but... The report below says stuff like "Info: Fix the reported corruption," and since this phone is my daily driver I don't want to be walking around with a corrupt filesystem that might brick the phone at any moment. Should I just do a factory reset? Is there any other way to fix filesystem errors? (e.g. on a windows device I know I could do sfc /scannow. Does Android have something similar?)
