Samsung a52s constantly freezing then restarting

[voidfern]

Around 30-45 minutes ago I opened my secure folder for the 1st time in a while and was browsing the gallery when my phone completely froze for around 1-2 minutes, then rebooted. Ever since then it keeps doing it even if I'm not using it and haven't even unlocked the phone -  it will be fine for a couple of minutes, then freeze, then reboot. I haven't had an update in a while so unless one happened without my knowledge it's not caused by a recent update. I also haven't backed up my phone in a while so factory resetting the phone to fix this would be a last resort.
