thumbnails no longer show for no reason

My jpg thumbnails are not showing up all of a sudden, I did not update my computer, it just stops showing thumbnails. i use activity monitor to force quit thumbnail.agent and relaunch the launcher and then it works for the most recent folder i viewed, but no other folders show thumbnails. i have restarted my computer several times and the same error happens. I am on a macbook m1 with sequoia 15.8


again i have not updated anything on my computer and thumbnail.agent no longer works. i have checked and unchecked "show icon preview" but that doesn't help either

If you are using a third-party Thumbnail agent, manager or generator...?

Then you need to check with them for support and/or a solution.
