The current version of macOS is 27.0.1. Based on your post you are running an older version, so the first step is to update your Mac to the current version.

The second step is to toggle the setting to Show Results from Clipboard off then back on, with a reboot in between.
- Go to System Settings
- Click on Spotlight
- Scroll down to the Results from System section
- Toggle the setting off.
- Select Apple menu > Restart...
- After the Mac boots up, follow the first three steps above and toggle the setting back on.

If that does not work, then see if the problem is present when you boot in safe mode. That process performs some system cleanup and clears caches, and also disables 3rd party extensions that may cause problems.

If that does not correct the issue, test in a new user account. A newly-created user account will have all settings at default, and if the issue does not occur in that new account then it provides guidance on what may need to be changed to correct the issue.

Once the testing is complete, the new account can easily be deleted.

Those steps will help to isolate the problem.
It might help to download and run EtreCheck, written by a long-time forum member. The free version is fine. Post the full report using the Additional Text button. No personal information is revealed.

Troubleshooting is needed because this does not appear to be an intrinsic issue with macOS 27.0.1. I cannot replicate your issue. In Safari, I selected the title of your post and copied it, then selected and copied several individual paragraphs in your post. They show up in reverse order in a clipboard search for 'spotlight' in Spotlight.
