Please follow the below steps:

1. Download the DisplayLink Support Tool available here
2. Disconnect your docking station from your computer for a moment - so you are able to log into your computer.
3. Run the DisplayLink Support Tool.
4. Then select Advanced in the left top corner of your top menu bar and once expanded select Reset Screen Layout
5. Then restart the machine, connect dock again and try to log in - this may require to setup your layout one more time.

The DisplayLink Support Tool worked for me. Thanks!

I have tried it all, still not working. Up until my update from Sonoma i've had no problems..

I have found that removing the Displayport from the dock (Lenovo) makes that the App won't crash. Only a HDMI connected gives me no errors but also no screen. It will give me the "sharing" icon in the top bar.

As soon as I add the Displayport, no matter what port, it shuts the app down and only the usb hub still works.

- Removed plist files with and without the tool.
- Used the info tool to remove the layout.
- Reinstalled windowlink manager app
- Tried older version
- Tried much older version.

Just set the monitor that was registering to 30 HZ and it shows up. (always worked on 60Hz).
Then adding the displayport monitor (4K) and they both stop working again, not even showing up.

--- Second update.
After setting my 4k monitor to Freesync it works again. HDMI monitor still wont go higher as 30Hz. At least it won't quit the app anymore. Now i need to get a second displayport cable, to test Freesync on the second 4K monitor.
