Can't authorise Max 7.3.6 on Mac OS Monterey 12.5

I haven't used my copy of Max for a while and I'm being asked to authorise in order to save. The window remains blank do I can't do so. I've done a clean install and start with no success.

I'm using Max 7.3.6 on Mac OS Monterey 12.5. Any help would be much appreciated so that I can make and save my patches. Thanks.
