Comment (by da5f656f):

 I believe that this issue is exacerbated by Cloudflare's new "Speed Brain"
 feature which is auto-default on all free plans since September 25.

 This user documents how Speed Brain caused errors with deleting posts and
 media:
 https://community.cloudflare.com/t/cloudflare-speed-brain-feedback-
 wordpress-delete-trash-errors/722992/2

 "Today we are very excited to share the latest leap forward in speed:
 Speed Brain. It relies on the Speculation Rules API to prefetch the
 content of the user's likely next navigations."
 https://blog.cloudflare.com/introducing-speed-brain/

 This could indicate that these specific issues are more likely to occur
 when using Chrome/Edge and Cloudflare's free plan.

 I tested this on a live and staging site, same server (WordPress 6.6.2,
 PHP 8.2.18.) I received errors when updating plugins on the staging site.
 Turned off Speed Brain and was able to update the live site with no
 errors.
