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.

I tried wiping everything and started from scratch. Huge hours put in... same issue. 70-80% CPU and max fan caused by com.apple.quicklook.ThumbnailsAgent (4988). It can be killed but starts right back up. I'd kill every thumbnail on my Mac if it would stop this.
Its been more than a year since this bug is persisting. Is there anyone testing Monterey? I hope its not there in Monterey!
I closed the opened Finder windows. The CPU automatically slowed down and the fans went quiet.
2018 Macbook Pro running Monterey 12.1 it's Thumbnailextension_macOS now but can confirm it's still an issue. I have to force quit it about once a day or it kills 99%+ of CPU. I can always tell when it's going because my fans spin up for no apparent reason.
This Error persist on osx 12.6 "Monterey"
How to reproduce this error:
press "Space" for preview on large 3D file, "STL, OBJ" point cloud. In 5 mins you can say good bye to your CPU and Memory because it's consumpt to 90%.
