This is a known kind of issue that can appear after an iOS update. Since your iPhone 12 is stuck at maximum volume I would suggest trying out these quick steps to see if this solves your issue.

Check the Basics

Make sure the Volume buttons are physically working. Press Volume Down and see if the onscreen indicator changes.

Go to Settings → Sounds & Haptics → Ringer and Alerts. Try moving the slider. If it doesn’t move, this confirms a software issue.

Restart Your iPhone

A simple restart can often fix post-update glitches.
- Press Side button + Volume Up/Down → Slide to power off → Turn back on.

Reset All Settings

This resets system settings (volume, network, display) but keeps your data.

Go to Settings → General → Transfer or Reset iPhone → Reset → Reset All Settings.

- After the reset, check the volume slider.

If the volume still stays at maximum, it could be a software glitch from the update.

Backup your iPhone via Finder or iCloud.

Try updating or restoring your iPhone in Finder (similar to what we discussed with your earlier issue).

DFU mode restore often fixes stubborn post-update bugs.

If still no luck after I would refer to contacting apple support directly where they will be able to offer you further assistance.
