How to stop 'USBServer' or 'NetServer' pop-ups after upgrading to macOS Sonoma on my Mac?

I've upgraded to Sonoma. Now, every time I start my Mac I get two

pop-ups: 'USBserver (or Netserver) would like to access data from other

apps - Don't Allow/Allow'. How do I stop or resolve this?

I found the very same question marked as resolved here: Pop-ups after Sonoma update - Apple Community

In fact, I do have a Brother printer connected to the Mac, but my Library / Printers folder is empty, so I do not know how to locate the files that are supposed to be removed.

Any ideas?

Thank you!
