I run all the Waves Plugins without problem.
I’m on the latest Win10 and CbB release as well.
The reason for telling you this is to try and give you the confidence that a) the problem isn’t universal and b) that you can get it to work.
If you can’t get help on the forum, contact Waves support by phone or email. They are excellent and will work with you.
All the best.
BTW, in addition to the post above; the Cakewalk scanner should only run when there’s a new plugin found, even if set to Scan on Startup which is the recommended and default setting. If the scanner hangs it’s often the case that there’s an error message hidden behind another open window that requires some action on your part. The scanning process will sit there until you clear the message.
