IPhone SE randomly won’t take screenshots anymore

I have an iPhone SE from 2016 and it’s still operational so I haven’t bothered upgrading. I have always reliably been capable of taking screenshots within apps on my phone by pressing the home and on/off button simultaneously. Randomly just yesterday whenever I attempted to take a screenshot within any app I had open on my phone (so it’s not just limited to one app or a result of an upgrade to a specific app) it would immediately exit me out of the app I had open and bring me right back to the home screen. Once again, I’ve tried this with multiple apps on my phone, all of which have been regularly successfully screenshot from prior to this. I have no idea what could’ve brought this on, or if it originated from me accidentally swiping a setting without realizing, or where I would navigate to in order to resolve this if it were in fact due to me inadvertently altering a setting on my phone.

I have already tried rebooting/restarting my phone. That didn’t change anything.

I would greatly appreciate any advice. Thank you.
