Pro-Q4 license issue on OS 15.5 M4 Max

When installing the Pro-Q 4 plugin on a new Macbook M4 Max running macOS Sequoia 15.5 (latest update).

After installing Pro-Q 4 consistently prompts me to re-enter the license key every time I reopen it, and shortly after doing so the plugin stops functioning. The license prompt reappears even after successfully entering the key and restarting the system.

We have already tried reinstalling the plugin, but the issue persists. The installer was downloaded directly from your website, using the most up-to-date version available.

Thanks
