License activation has stopped working after upgrading to macOS Sequoia (version 15)

I have activated CrossWorks on my macOS machine and have been using it for some time but today I upgraded to macOS Sequoia and I am now getting a "No installed licenses..." error. Also, if I request a new activation, the license manager now says "No Ethernet adapter detected on this PC". What could have caused this and how can I fix it?

macOS Sequoia includes a new feature called MAC address randomization which is enabled by default.

Named developer licenses on macOS are locked to MAC addresses so a license will become invalid if it is locked to the Wi-Fi adapter and the MAC address changes.

The randomized MAC addresses are also not eligible as a lock addresses so they will not be listed in the dialog when requesting a new activation.

To disable MAC address randomization:

1. Click Apple Menu > System Settings...
2. Select the Wi-Fi tab in the sidebar
3. Click the Details... button
4. Set the Private Wi-Fi address option to Off
5. Click OK button to apply the change

Alternatively, use a wired network adapter and lock the license to that when requesting a license activation.
