Try going to the App Store and searching for macOS Monterey. If you find it you should be able to download and install it.

Hello Jamie!

Usually, when this happens a power cycle will resolve the issue. Navigate to the Apple menu in the top left, and select restart.

Hope this helps!

Give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.

NOTE: Safe Mode boot can take up to 3 - 5 minutes as it's doing the following; 

• Verifies your startup disk and attempts to repair directory issues, if needed

• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)

• Prevents Startup Items and Login Items from opening automatically

• Disables user-installed fonts 

• Deletes font caches, kernel cache, and other system cache files
