I am also not able to reproduce the issue.
You could first try to reinstall the core files

Otherwise, I completely agree with @krishnagandhicode – please check whether you have a third-party extension that might be causing the problem here?

OK I'll examine my extensions and core files. Closing the issue.
Hi @mambroziak
I tried to reproduce this on a clean Joomla 5.4-dev install but it sorted for me.
However according to me looking at your error logs, I see THE WARNING Undefined property: stdClass::$creationDate(which is used to sort) means that Joomla is trying to sort the list of extensions, but at least one of the extensions installed on your site is missing the creationDatee data in its XML file.
This error is most likely being triggered by a specific 3rd-party extension you have installed ?
