I've contacted MacPaw support to give them a chance to address this:
Hi,
I'm having an issue with Swap Memory. I'm running the latest version of Final Cut Pro 10.4.8 on a 2015 MacBook Pro (OS 10.15.5). Over the course of 10 minutes, every couple of hours, the Swap Memory goes up from around 1-2GB to 55GB then Final Cut Pro crashes. I've put this question to Apple DIscussions and am pointed to the feed "cleanmymac claims another victim". I am advised to do a clean install, removing CleanMyMac (v4.6.5) in the process. Can I have a response from you before I do this?

As I am halfway through several editing jobs, I'm loath to do a clean install but will if Swap Memory continues to haemorrhage.
Thanks for your help.
Sebastian
