Ventura 13.4.1 update - issues with external USB memory sticks

13.4.1 is causing problems with external USB memory sticks.

When I plug in a USB memory stick I get a continuous cycle of "Disk not Ejected Properly" messages.

This occurs whichever port I plug the USB stick in to (via an adapter if necessary).

See screen grab......

Mac Studio, macOS 13.4

that's because Mac OS is NOT like Windows! Mac OS is based off BSD Unix and so a user must mount and dismount externals and NOT just unhook them util you un-mount the external then remove the drive! It's really easy just drag the external mount drive and drag to the Trash or the keyboard warrior mode highlight external mounted drive and press at the same time the letter e will also unmount the external!
