Unable to make any HTML snapshots with docker latest-plus - "Check failed: VerifyChecksum(blob)."
New installation with docker, using latest-plus. For any url that I try to bookmark (using the web ui, not the browser extension which I've not tried), I get the following in background_tasks.log :

Viewing the bookmark shows no files, with the error message HTML snapshot from 05/21/2025 (failed)
I copied the .env file but didn't make any changes other than to set up a Superuser, as I'm not using any kind of auth_proxy.
I run in a similar issue. Also trying to create HTML snapshots getting the following output as one example:
