Trouble upgrading from Ghost 4.41.3 to 4.48.2

Hello! I’m looking to upgrade to Ghost 5. Following the upgrade guide, I’m currently trying to update from 4.41.3 to latest v4 (4.48.2). But I get the following error upon booting the updated Docker container:

I searched the forum and GitHub issues and didn’t find anything related to no such file or directory during the Creating database backup step. Has anyone seen this issue, or can provide guidance on how I can solve this?
