dynamicmedialinkserver is using huge resources on my computer

Question

When I look at my Activity Monitor, the dynamiclinkmediaserver is using 99%+ of my CPU. Even when all of my major applications are closed, and everything is idle, about 35% is being used. What is this thing doing? I'm using a Mac desktop with 28GB of memory and macOS Catalina 10.15.1. I have an Adobe CC full subscription and all of my Adobe apps are up-to-date.

From the searching I've done, it seems like this has been a problem for many Adobe users for quite a while. Why isn't Adobe doing something about it? I'd like to get rid of the problem, it's very frustrating. I'd appreciate any thoughts. Thanks.

dynamiclinkmediaserver is part of Lightroom's video support. The same service is also used by multiple other Adobe applications.

It can be stopped using the Force Quit option in Activity Monitor (i.e. select the process then click on the Stop button which can be found at top left corner of Activity Monitor window).

If the process restarts again then try resetting Lightroom Preferences using Method 1 described at https://helpx.adobe.com/lightroom/help/setting-preferences-lightroom.html

If above doesn't reslove the issue then try purging the video cache in Lightroom preferences panel.
