After inactivity the lock screen used to kick in but recently has stopped working, this is now a potential security issue. In settings the lock screen 'Require password' has been greyed out so I'm at a loss as to how to get it back.
Mac mini, macOS 26.3
If you manually sleep, the Mac from the menu, does it stay sleeping and does the lock screen appear after waking it assuming the appropriate amount of time has passed?

That will happen if you have FileVault enabled (default on in Tahoe) or iPhone Mirroring enabled. However, the Lock screen should function as it always has.
When is it set to activate?
…and the iPhone is usually not mirrored
It’s the setting, not actually mirroring at the time. If it is allowed to mirror, you are prevented from changing the password required setting.
There is more to this problem, though as the setting is grayed out because it must be on in those two situations (perhaps there are more). Something is preventing it from locking. Can you manually go to the Lock Screen from the menu?
Sorry about the delay. I've done as suggested and the 'require password' is no longer greyed out. The problem is still there however as I've only just realised that the display is not turning off regardless of the time set - be it 10minutes or one. When finishing I turn off the monitor manually and don't usually wait for the setting to activate.
When switching the monitor back on there is still no lock screen.
It's set to come on if inactive for 10 minutes. I've turned off the file vault and the iPhone is usually not mirrored but doesn't appear to have made a difference - the password option is still greyed out.
I thought it was in the Airplay & Continuity settings, but you may just have to disable it on the iPhone Settings.
I had thought there were settings to enable asking for unlock, but can't find them now that it is disconnected.
I have turned mine off as I found it essentially useless. It would always ask to unlock the iPhone to use the mirroring function. If I had the iPhone at hand to be able to unlock it, I would have just used it.
Yes I can still go to lock screen from the menu. How do I disable the mirroring?

Open the iPhone Mirroring App on your Mac mini and change the setting to "Ask every time"
Thanks for the help. Lock screen still not appearing so will have to activate it manually for the time being.
Lock screen not working; 'Require password' greyed out
