@ivnj, I think @chabig is getting you to look at the wrong sort of extension. Have a look at this https://discussions.apple.com/thread/254614941?sortBy=best Is something similar what you can see in System Settings. In that case just click the Allow and restart.
Open terminal and enter the command “systemextensionsctl list”
This will list the system extensions. You may see one in an error state or some other state that might help identify what program is trying to load the extension at startup. Sometimes reinstalling that app will help with getting the extension to load, or prompt you to allow in system settings

Only other thing I can think of is to open the console app and see if there are any errors there that might point you in the right direction.
Normally, system extensions are used by antivirus software, backup software etc. That’s where I’d look first.
Also, what happens when you click open system settings on the dialogue you posted in the or post?
What is in these 2 folders (ideally nothing)?

/Library/SystemExtensions/ and its subfolders?You have to go down one level to discover the identity of the system extensions. Like this:

Tidying up this sot of thing can be difficult because Apple protects all the folders above. I don't do this sort of thing often, but suggestions:
1) If you can identify the likely app, you could uninstall it fully and reinstall - or maybe just reinstall without uninstall.
2) You may be able to remove
Any changes will require a reboot to be complete, because the kext cache needs to be rebuilt.

@gilby101 , you know way more than I do. The error shown in the opening post complains about system extensions, not kernel extensions (kext file extension). Are they just being careless with their language? It does seem like a kernel extension issue since they mention "rebuilt" in the message.
Apple's support document says that you have to boot into recovery mode to enable kernel extensions. Perhaps doing that would allow the os to fix things up.

System extensions in macOS
Kernel extensions (kexts) risk the integrity and reliability of the operating system, and so users should prefer solutions that donʼt require extending the kernel and use system extensions instead.
