After upgrading to macOS Sequoia 15.4.1, I noticed that DisplayLink Manager no longer works as expected. External monitors connected via DisplayLink are not being detected, and the DisplayLink Manager app either fails to launch properly or shows no connected displays.

Before the update, everything was working normally with the same hardware and configuration. I’ve already tried the usual steps such as restarting the system, reinstalling the latest version of DisplayLink Manager, and re-granting permissions under Privacy & Security (Screen Recording, Accessibility, and Input Monitoring), but without success.

It seems likely that the 15.4.1 update introduced changes that affect DisplayLink drivers or required system permissions. I’m posting this to see if others are experiencing the same issue, and whether there’s a known workaround, beta driver, or compatibility update planned from DisplayLink FNAF Free.

Any insights or confirmed fixes would be greatly appreciated.
