Then you'll have to downgrade back to Monterrey! Is there any way to keep all the data and downgrade without erasing the startup disk? I have an urgent task to do on my Mac right now, and it just happened to me.
MacBook Pro 14″, macOS 13.0
If you have enough free space, you can downgrade to a previous operating system if your Mac supports it. You can always make a separate boot on an external hard drive to read the data on your upgraded system.
Note Sierra older systems, can't read solid state High Sierra systems or later, or APFS formatted volumes on High Sierra or later.
If you open Photos or your music library to upgrade it to a newer system only the photos will be visible, and not the library or playlist files that were upgraded. You can search for individual files by name with Devon Technologies EasyFind.
If there are specific files you want to read in a newer system that you haven't found an application for yet, ask here, and we may be able to help you find it, so you don't have to downgrade.

You will need to erase the startup disk.
First, create a Time Machine backup if you have not done so already: Back up your files with Time Machine on Mac - Apple Support.
Then, you may have some options.
