Under Catalina Beta2 I am noticing that the process com.apple.quicklook.ThumbnailsAgent CPU is consistently consuming between 70% - 90% on my MacBook Pro 2016. I've tried killing the process but it restarts and goes back to consuming the same excessive amount of CPU. Any ideas on how to get this to stop are most appreciated.

Reporting from Big Sur 11.4:Same issue. I tried following in the terminal to kill the process
% kill 15 com.apple.quicklook.ThumbnailsAgent
% kill <the_processid_for_com.apple.quicklook.ThumbnailsAgent>
% sudo killall com.apple.quicklook.ThumbnailsAgent
But it kept running. Then I “force-killed" it from the Activity Monitor. No heat so far.
