Hi Knidianaphrodite,
You have done some great steps to resolve the issue. The next step would be to restart the device using the steps here: Restart your iPhone - Apple Support that are also listed below.
"How to restart your iPhone X, 11, 12, 13, or later
- Press and hold either volume button and the side button until the power-off slider appears.
2. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.
3. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo."
If the issue still occurs after the restart, then please reach out to support for further assistance here: Apple Support
Best regards.
