SharePoint Framework - gulp serve unknown error

Question

Hello, I wanted to create a SharePoint Online extension and have set up my environment according to these instructions: https://learn.microsoft.com/en-us/sharepoint/dev/spfx/set-up-your-development-environment

The versions of the individual components fit together. I have taken them from this table: https://learn.microsoft.com/en-us/sharepoint/dev/spfx/compatibility#spfx-development-environment-compatibility

When I want to start the application with gulp serve I get the following error: "'serve' errored after 24 s [09:15:24] Error: UNKNOWN: unknown error, watch at FSWatcher._handle.onchange (node:internal/fs/watchers:207:21) at FSEvent.callbackTrampoline (node:internal/async_hooks:128:17) About to exit with code: 1 Process terminated before summary could be written, possible error in async code not continuing! Trying to exit with exit code 1

I can't find a solution to this problem.

Can anyone help me?
