I’ve updated to 4.14.1 without an issue, I expect the article about the new version has yet to be written / published, perhaps check your web server / PHP logs to see if there are any errors that might indicate the problem with your instance?
[22-Mar-2023 09:00:02 UTC] PHP Fatal error: Uncaught Error: Class "ComposerAutoloaderInita8589bba0fef171abd252f715538f151" not found in /home/tcloudde/analytics/vendor/autoload.php:25

Meanwhile I fixed the problem by downloading the new version 4.14.1 as zip and copied the extracted files of the vendor folder to my current installation.
After this, I got the console working again and did a console diagnostics:run which found some other files with wrong checksums in lang and plugins dir.
After copying them as well over my existing system all runs well again.
