Bridge takes up 90% CPU for 10 minutes after creating thumbs/previews on 200 raw files

Hi, my name is Thijs. I use Bridge all the time to browse my raw files, open them via ACR into Photoshop. Since around Dec 1st, Bridge is taking up 90-100% CPU for minutes, even after finishing creating thumbnails and previews. I noticed it because Photoshop was laggy. Before, Bridge would take up a considerable amount of resources to create thumbs/previews, but would settle down immediately after. To give you an idea: on a folder with 200 CR2 Canon raw files, it takes appr. 50 seconds to create thumbs/previews. But then it goes on for about 10 minutes at 90% CPU. And it takes appr 3.5 GB RAM. This leaves Photoshop very laggy, hard to work with. When I switch to another folder with only a few small jpgs, the CPU slows down to 2%. When I focus back on the original folder, it goes back up to 80-95%.

The problem seems not to occur with jpgs and tiffs, so it might also be a Camera Raw issue?

I'm on Windows 10. My computer is an i9 with 64GB RAM, and an NVIDIA GTX 1060 6GB graphics card. All CC-applications are up to date, only PS is 22.0.1.

What has changed in the past few days and may be related: I installed Premiere Pro.

What I tried to fix it:

- restart the computer.

- uninstalled Bridge without preserving settings, and reinstalled.

- I tried to reset the Bridge preferences by holding ctrl alt shift at startup, but I never got a menu so I don't think that worked.

I cleared the entire Bridge Cache, and the Camera Raw cache.

- checked the video card driver: it is up to date

- Adobe Camera Raw has been updated to 13.1.0.658
